| Abstract | Polymer-modified mortars (PMMs) are prepared by using dispersible polymer powders or powdered emulsion (powered cement modifiers) and aqueous polymer dispersion (aqueous cement modifiers) with various polymer-cement (P/C) ratios. Specimens are made with the help of moulds and cured. Different tests like compressive strength, flexural strength, tensile strength, maximum deflection, maximum extreme tensile fibre strain, maximum tensile strain and adhesion in tension or bond strength are performed for the cured specimens. Afterward, powder samples are made from the broken specimens, which are then subjected to X-ray diffraction, differential thermal analysis (DTA) and thermal gravimetric analysis (TGA). From the test results, it is concluded that the formation of calcium hydroxide (Ca(OH)2) is reduced in (PMMs). Whereas, on the other hand, their compressive strength, flexural strength, tensile strength, maximum deflection, maximum extreme tensile fibre strain, maximum tensile strain and adhesion in tension or bond strength have been improved. However, variation in the above- mentioned properties depend upon the P/C ratio and cement modifier used or both. It has been concluded that the reduction of Ca(OH)2 content in PMMs does not cause any detrimental or adverse effect on their strength, elastic and adhesion properties, they are improved. |
