Comparative tests of cements in concrete mixtures of high mobility

The paper presents the results of comparative tests of imported and local cements in highly mobile concrete mixtures of various classes and brands. It is proved that on the basis of local cement it is possible to obtain concrete of any grades in terms of workability and grades in compressive strength up to B45. Various factors affecting the stability of the composition and properties of the concrete mixture are considered. Recommendations on their use in high strength concrete are proposed.
