In this work the the influence of two silanes on macroscopic properties of fresh and hardened cement pastes and mortars prepared from ordinary Portland cement are presented. The highly polar amine and alkoxide groups of aminosilane molecules exhibit strong chemical interactions with cement matrix. Their influence is demonstrated in higher workability of fresh cement mortar, longer setting and higher strength after prolonged curing. These effects on cement system can be exploited in the formulation of composite cementitious products like cement based corrugated plates.

In the contribution the theoretical consideration of applicability of Weibull distribution for the evaluation of ceramic and composites strength values. The results are useful since the determine the range in which the use of Weibull statistics is reasonable and correct.
