INVESTIGATION ON PORTLAND CEMENT PASTES AND MORTARS MODIFIED BY THE ADDITION OF EPOXY. IN: POLYMERS IN CONCRETE. INTERNATIONAL SYMPOSIUM

The paper reports on laboratory experiments that aimed to show the effects of epoxy modification of portland cement mortars in the presence or absence of accelerating and/or plastifying admixtures. One series of control and eight series of modified Ottawa-sand mortars were prepared for the testing of the flow as well as the compressive strength. The study also investigated the effect of epoxy addition on the hydration of portland cement mix on two series of control and ten series of modified cement pastes by using a new method, the silylation. Considerable improvement was shown in the workability of the epoxy-modified mortars, as well as strength increases, when an accelerating admixture was used. The results of the silylation indicate that these strength increases were caused by physical factors.
