Sažetak
This paper presents novel results on properties of Styrene-Butadiene-Rubber (SBR) latex modified mortar based on Calcium aluminate cement. This mortar can be advantageously used for rapid repair works. Mortar specimens with constant consistency (160 ± 10 mm) and constant W/C ratio were prepared with river sand (0 – 4 mm). Solid content of SBR latex was varied as 0%, 3%, 6% and 9% of cement mass. Specimens were tested after treatment at different curing conditions: 1 and 7 days at room temperature and subsequent transformation at 70 °C. Examined properties of latex modified repair mortar are consistency of fresh state mortar, adhesion in tension, flexural and compressive strength, dynamic modulus, total, open, and closed porosity of hardened mortars. Adhesion to concrete substrate was investigated on specimens with 0% and 9% of solid content. The measurement results indicate that SBR latex improves workability of fresh state mortar and thus enables a reduction in mixing water content (W/C). Stiffness decreases while flexural and adhesion strengths increase with latex content addition in mortar specimens, due to polymer coagulation process and co-matrix formation.
