Effect of Silicate Additives on the Impact Strength of Cement Pastes

Wiktor Szewczenko , Galyna Kotsay


In construction, the usage of silicate additives is constantly expanding. Depending on the type and amount of mineral additives and the time of cement hydration, the structure of basic cement hydration products varies and it affects the properties of cement pastes. To ensure general-purpose cements of high quality, it is necessary to monitor constantly of activities of used mineral additives. To investigation of activities of additives used physical and chemical methods. However, during continuous production, such methods are time consuming, so, it is necessary to use some quicker way to check activities of mineral additives in cement. Therefore, in the paper, impact bending strength method is proposed for evaluation of mineral additives’ activity. However impact strength of cement pastes depended on curing conditions. Unbound water in capillary and gel pores works as shock-absorbent during impact bending tests. Therefore, impact bending tests, should be performed on samples stored in air-dry conditions.
