Abstract

This database is a useful tool in the construction industry, ensuring that building materials comply not only with technical standards but also with radiation safety regulations. In the past few years, the cement industry has used so-called SCMs to reduce the carbon footprint of cements, without considering that these SCMs (supplementary cementitious materials) are mostly NORMs (Naturally Occurring Radioactive Materials) that may contain variable levels of radionuclides, primarily 226Ra (of the 238U series), 232Th and 40K. These levels must be controlled in the final construction product, as required by regulations (EU Directive 2013/59). This paper presents data on the activity concentration of natural radionuclides in cements, SCMs, aggregates, and mining and ceramic wastes that are likely to be used as SCMs in the future. Specifically, it presents the chemical composition of these materials alongside with their radionuclide activity concentration data obtained by gamma spectroscopy. These results serve as a database that can be used in different studies to assess the possibility of using these materials in construction materials in compliance with European regulations on radiation protection.

Data collection The oxide composition of the materials was determined using an S8 TIGER X-ray fluorescence (XRF) spectrometer (Bruker). Loss on ignition (LOI) was measured in accordance with the European standard EN 196–2:2014 [1]. For XRF analysis, samples were oven-dried and finely ground to achieve a particle size below 63 µm.
Radiological characterization was performed by gamma-ray spectrometry employing a system equipped with five high-purity germanium (HPGe) detectors: two XtRa (extended range), two BEGe (broad energy) and one REGe (reverse electrode), ensuring high-resolution detection over a wide energy range. For radiological measurements, to ensure secular equilibrium between 226Ra and 232Th and their progeny, the samples were placed in hermetically sealed cylindrical plastic containers (75.4 mm diameter × 31 mm height), completely filled to minimize voids and radon escape. The samples were stored for a minimum of 25 days prior to measurement to allow equilibrium to be established. All measurements were performed in duplicate to ensure reproducibility.
Data source location The samples come from a wide range of places: many are from Spain, but there are also samples from Portugal, China, Chile and many other locations.
All the samples were collected by the IETcc-CSIC through different collaborations. XRF was performed in IETcc-CSIC and an aliquot of the samples was sent to CIEMAT to determine the gamma emitters using high-resolution gamma spectrometry (HPGe). The samples were recorded in an Excel spreadsheet, indicating the date of receipt, origin, date of preparation, and finally their chemical composition.

1. Value of the Data

The dataset presented constitutes a valuable source of information on the natural radioactivity present in building and construction materials.

  • •

    The data presented herein can be used as an on-line database of the natural radioactivity of materials used in different types of building materials, that facilitates the comparison, analysis and evaluation of radionuclide concentrations in different types materials.

  • •

    For researchers in the field, these data may serve as a reference for other studies on natural radioactivity in construction materials, in geological and/or environmental studies that analyse the distribution and concentrations of natural radionuclides (such as ²²⁶Ra, ²³²Th and ⁴⁰K) in these materials.

  • •

    The data can be used for potential radiological safety assessments, as they allow the calculation of the absorbed dose rate, the annual effective dose and the activity concentration index (ACI), which are key indicators for determining potential exposure to ionising radiation in residential or occupational environments.

  • •

    The results can be the basis for the calculation of the activity concentration or excess effective dose rates described in the European Union Directive 2013/59 [2] for final building materials.

2. Background

In recent years, the scientific community and social agents of different stripes have identified a pressing need for measures to curb climate change and favour the circular economy by lowering greenhouse gas (essentially CO2) emissions, optimising the use of natural resources and reusing industrial waste and by-products. Specifically, cement manufacturing is responsible for approximately 8 % of CO2 emissions into the atmosphere due to the high temperatures required to manufacture clinker (the main component of cement) and the decarbonisation of limestones. One solution is the development of high quality, low environmental impact mortars and concretes, entails valorising such industrial waste and by-products to reach sustainability goals. So-called green concretes are sustainable materials to which a number of types of waste are added with no detriment to strength or durability. Another way to improve sustainability is to use cements with supplementary cementitious materials (SCMs) to replace part of the cement clinker. However, these SCMs and some sustainable mortars and concretes may contain waste classified as naturally occurring radioactive materials (NORMs) or geological materials with a high radioactive content. Electric power station fly ash, blast furnace slag, phosphogypsum refuse and red mud are a few examples of NORMs-bearing waste. To be apt for use in building materials, NORMs must exhibit suitable technological characteristics and properties without constituting a radiation hazard for living beings or their environment. The general objective sought with this study is to determine the effect of NORMs waste and geological materials with high natural radionuclide contents on the levels of radioactivity by sustainable mortars and concretes and to guarantee the safety of their use by complying with regulations on the exposure of people to ionising radiation, and also to be compatible with environmental protection.

3. Data Description

This work presents the dataset from the Digital CSIC linked repository corresponding to data obtained from materials that can be used in building materials. The measurements were taken between 2020 and 2025 as part of the PID2020–116002RB-I00 project.

A total of 162 samples of different types, suitable for use in construction materials, have been analysed. Tables 1 to 4 show the chemical composition values for each sample, divided according to raw material type. Following the same criteria, Table 5, Table 6, Table 7, Table 8 show the radionuclide activity concentration index data for these same samples.

3.1. Chemical composition of materials

This section presents the chemical composition of all materials along with their loss on ignition. A brief description of the materials accompanies these data. shows the oxide chemical composition of 18 different cement types:

  • -

    Ordinary Portland Cement (OPC) Type I (95 % clinker) [3]

  • -

    Sulphate resistant, with limited content in C3A [4]

  • -

    Belitic. Type I Cements with higher content in C2S than in C3S.

  • -

    CAC, with different chemical and mineralogical composition than OPC, whose main phase is monocalcium aluminate CA [5]

3.1.1. Supplementary cementitious materials (SCMs)

Table 2 shows the chemical composition data of five common types of SCMs

  • a)

    Fly Ash (FA): Type F (FA1-FA15) and two Type C fly ash (FA16–17) [6].

  • b)

    Slags (S): Blast furnace slags (S1-S9), steel slag (S10-S11), zinc slag (S12), copper slags (S13-S15).

  • c)

    Clays (CL). kaolin (CL1-CL5), other types of clays (CL6-CL13)

  • d)

    Red Mud (RM1-RM3).

  • e)

    Biomass ash (B1-B4).

4. Experimental Design, Materials and Methods

This section describes the procedures and techiques used to obtain data from 162 cementitious samples.

4.1. Experimental design

First, the samples were classified by typology. Next, a small portion of approximately 10 g of each sample was used for chemical analysis by FRX, and another portion of approximately 500–600 g was used for radiological characterization [7].

4.2. Raw materials

In this study, a total of 162 samples were analysed during the development of the PID2020–116002RB-I00 Project “Sustainable mortars and concretes: natural radioactivity, radon exhalation and interaction with the environment – HORRADIONEX”.

Commercial Cements: Eighteen cements from the following classes have been analysed:

  • a.

    Eleven Type I cements (CEM I 42.5R y CEM I 52.5R) from different cement factories (samples C1-C11), according to European Standard EN-197–1–2011 [3].

  • b.

    Two CEM I 52,5 S/R, sulphate-resistant, characterised by a lower content in calcium aluminates (C3A) (samples C12 and C13) [3,4].

  • c.

    Two belitic cements with a lower C3S content and a higher belite (C2S) content than Type I cements (Samples C14 and C15) [3].

  • d.

    Three calcium aluminate cements (CAC) (samples C16-C18) whose main component is monocalcium aluminate (CA). This type of cement complies with European standard EN 14,647–2006 [5].

Supplementary Cementitious Materials: 52 SCMs from a wide variety of sources, some of which are commonly used in the preparation of cement-based materials and others are emerging or future supplementary materials.

  • a.

    Fly ash (FA): fifteen coal fly ashes (type F) from different locations (samples FA1-FA15) and a two Type C fly ashes (FA16-FA17) [6].

  • b.

    Slags (S): Fifteen slags with different origins and compositions: Blast furnace slags (samples S1-S9), two steel slags (S10-S11), one zinc slags (S12), and three copper slags (S13-S15). Slags are by-products of the metallurgical production of iron, steel, copper etc.

  • c.

    Thirteen clays (CL) from different places.

  • d.

    Three red mud (RM) that is a solid waste with high iron content, generated in the industrial process to produce alumina from bauxite.

  • e.

    Four biomass ashes (B)

Aggregates: fifty one aggregates with different geological origin.

  • a.

    Nine siliceous aggregate (samples A1-A9).

  • b.

    Three feldespaticc sands (samples A10-A12).

  • c.

    Eigth carbonatic aggregates (samples A13 and A20).

  • d.

    Four metamorphic aggregates (A21-A24)

  • e.

    Eleven volcanic aggregates from different geographical places (A25-A35)

  • f.

    Sixteen granitic aggregates (A36-A51)

Mining and ceramic wastes (W): a total of forty one wastes

  • a.

    Twenty three phosphate mining wastes which could be valorised, always bearing in mind that they may present high concentrations of radionuclide activity.

  • b.

    Four mining wastes other than phosphates ones.

  • c.

    Fifthteen glass and ceramic wastes that could be used as aggregates, or valorized in ceramic industry [8].

4.3. Methods

The determination of chemical composition of materials by XRF was in fuse beads.

The radionuclides determined in this study were those belonging to the natural radioactive series of uranium, actinium and thorium along with 40 K. The gamma emitters determined in the uranium series were: 234Th (63 keV), 214Pb (351 keV), 214Bi (609, 1120 and 1765 keV), 226Ra (186 keV eliminating interference from 235U) [9], 210Pb (46.5 keV). In the actinium series the activity of 235U (144 and 163 keV) was determined. For the thorium series the gamma emitters analyzed were: 228Ac (911 keV), 212Pb (238 keV) and 208Tl (583 keV). The activity concentration of 40K was determined by its characteristic photopeak at 1460 keV.

The efficiency calibration of the gamma-ray detectors was computed by using the mathematical code LabSOCS (InSitu Object Calibration Software) [10]. The samples were acquired and analyzed using Genie 2000 software [11]. The samples were measured for a minimum duration of 80,000 s to achieve the required detection.
