Book ChapterDOI
Sustainability of gypsum products as a construction material
TL;DR: In this article, the sustainability of gypsum products during their life cycle is considered, including the energy efficiency of different manufacturing technologies, the use of industrial wastes containing calcium sulphate dihydrate as substitutes for natural gypsuma, and recycling of the wastes from gypsume-based construction materials (plasterboards, moulds) where they arise.
Journal ArticleDOI
Using mathematical modeling for design of self compacting high strength concrete with metakaolin admixture
TL;DR: In this paper, a concrete design objective function is proposed to obtain the required concrete strength by minimizing the cost of the most unsustainable concrete components, like cement, metakaolin and superplastisizer.
Journal ArticleDOI
A method for optimal design of steel fiber reinforced concrete composition
TL;DR: In this article, the influence of the main factors (water-cement ratio, fiber content, fineness and quantity of sand) on the concrete mixture stiffness, compressive and flexural strength of concrete is investigated.
Journal ArticleDOI
Application areas of phosphogypsum in production of mineral binders and composites based on them: a review of research results
TL;DR: In this paper, the impact of phosphorgypsum as an admixture for clinker and non-clinker binders was investigated, and it was shown that using 2 to 2.5% of phosphoric acid as setting time regulator resulted in a similar physical and mechanical properties compared to mix made with natural gypsum.
Journal ArticleDOI
Design estimation of concrete frost resistance
TL;DR: In this article, a theoretical analysis of the proposed parameters of the structure of concrete, which determine its frost resistance, is carried out and a calculation formula for predicting the frost resistance of concrete depending on the ratio of the volumes of open and closed pores in its structure.
