“…Advances in the concrete industry add some uncertainty into construction markets. Wei et al (2018) assess that emission factors related to cement production in China could decrease by 59-69% by 2030 from the 2005 level, if CO 2 capture, use and storage (CCUS), use of alternative raw materials and fuels, and technological innovation took place. That would strengthen the market position of concrete from the environmental performance perspective.…”

“…In the case of concrete, the main limiting factor from an environmental point of view is the production of cement which is currently the most widely used binder in the construction industry with rapidly increasing production in recent years [1,2]. The process of cement production is highly energy-demanding with accompanying high environmental impact.…”

Concrete production unfavourably affects the environment due to high energy demands of cement production and consumption of limited natural resources. Therefore, waste utilization in fabrication of cementitious material is beneficial and legitimate. Significant reduction of environmental impact can be secured by utilization of various types of wastes or byproducts used for a partial substitution of cement binder or aggregates. However, the use of waste materials usually leads to deterioration of material properties of the designed composites. Therefore, it is very important to thoroughly investigate important materials properties to verify performance and practical usability of the newly designed materials. In this paper, three types of concrete mixes were designed. The reference concrete involved fine and coarse natural riverbed aggregates and two other mixes were designed using both, natural and recycled aggregates represented by crushed concrete paving cobbles. Concretes were tested in terms of basic physical properties (bulk density), mechanical properties (compressive strength), thermal properties (thermal conductivity, specific heat capacity, thermal diffusivity), and hygric properties (water vapour diffusion resistance factor, water vapour sorption at 97% RH, water absorption coefficient, moisture diffusivity) and experimentally determined data were compared and discussed. It was observed that materials properties of concretes with recycled aggregates are comparable with those of the reference concrete which is a promising fact from the environmental point of view.

“…Use of cement concrete on huge scale imposes a major environmental challenge during the production and it is a matter of high concern in the world market [2], [3]. To reduce the greenhouse gas emissions during production, different strategies have been extensively studied in the recent past [4]. Researchers have evaluated the performance characteristics of addition of admixtures in concrete in the past few decades.…”

Traditional testing methods such as absorption test and permeability test are normally not providing accurate results of nature of concrete and there is a need for another type of test to predict the durability of concrete. In this work, industrial by-product like dolomite, marble dust and fly ash are utilized as fraction of cement replacing with 2%, 4%, 6%, 8%, and 10% dolomite, 10% fly ash and 10% marble dust by the weight of cement. The study is conducted on mix designed concrete of M30 grade and compared with conventional concrete. The specimens are casted and tested to examine various properties of concrete like compressive strength, split tensile strength, durability and sorptivity. Durability test is done by hydrochloric acid (HCl) and sulphuric acid (H2SO4 ) on dolomite powder, promising results were obtained in the sorptivity test which shows the dense nature of concrete by the usage of dolomite powder.
