Premix PCC materials: mechanical properties as a function of technological factors
Abstract Mechanical properties, microstructure, dimensional stability and phase interactions of premix polymer-cement composite materials (PCC) were investigated as a function of polymer content, water/cement (w/c) ratio and preparation and curing procedures of the samples. The investigated PCC materials were made of normal cement mortar with the addition of variable amounts of water-soluble or dispersible epoxy resins and polyelectrolytes of different functionality. Mechanical strength (compressive and flexural), dimensional changes and microstructure after various curing times were then evaluated in comparison with the same parameters for plain mortar samples prepared by standard procedures. The results so far obtained show that a strong reduction of the w/c ratio in PCC materials can be obtained through polymer addition. Hence, a proper design of the mixing and curing procedures, combined with an optimum reduction of the w/c ratio, causes a remarkable mechanical strength increase in the PCC materials investigated.
