Resumo
Introduction. Concrete and reinforced concrete constitute the primary materials in the construction sector. As construction quality standards elevate, it is important to improve the quality of building materials. The quality of concrete is improved by incorporating finely dispersed mineral additives into cement. Their incorporation into cements enhances structural integrity and enables the development of next-generation modified binders. One of such additives is diatomite.
The aim of research is to develop concrete compositions using cement with the addition of modified diatomite.
Materials and methods. Portland cement of class CEM I 32.5 and CEM I 42.5 was used for the research. Diatomite modified with lime (DMI), diatomite modified with hydrochloric acid (DHV), diatomite modified with carbon particles (DMCMTS) served as mineral additives.
The strength of concrete was assessed against GOST 10180-2012 "Concrete. Methods for determining the strength using control samples"
Research outcomes. The research indicated that concretes with modified diatomite enhance the strength classification of concrete to B25 and above.
Conclusions. The incorporation of diatomite-modified cement in concrete production enables a reduction in cement usage by 15 % per cubic metre of the mixture.
