SHAPING THE STRUCTURE OF LOW WATER-BINDER RATIO CEMENT PASTES

Abstract eng:
Cement and aggregate composites constitute one of the basic structural and material solutions applied in civil engineering. A wide application range results mainly from the possibility of relatively flexible adjustment of required parameters, including the leading mechanical property which is the compression strength. As is known from the basic source literature, there exists an approximate proportional relation between the strength of a hardened paste and analogous characteristics of a cement paste and concrete, while the differences result from aggregate feeding. Considering the above, this paper describes selected issues and problems related to the design of cement composites of the assumed strength. Particular attention is paid to the problem of shaping low water-binder ratio cement dispersion.
