Removes. t Particle Board: High Density (TISI, 1994), to The results showed that the compressive strength of mortar was decreased with increase the percentage replacements of GRHA and LS in Portland cement Type V. At 180 days, the compressive strength of all mortars was lower than that of the control mortar. Note: Physical properties listed in Table 2 and Table 3 are measured â¦ Grouting . In addition, the strain-rate sensitivity of compressive strength of cement mortar will increase under attacks of sodium sulfate or sodium chloride solution. Mortars used to form soft layers fro bricks and stones in masonry work. On the basis of these considerations, variations in the strength and durability of concrete and concrete mortar have frequently been explained by differences in their fine aggregate (~-~). The ratio of water to cementitious material was controlled based on the water requirements conforming to flow value at 110 ± 5%. This study was aimed to indicate the inadequacies of the presently used methods for testing sulfate resistance of cementitious systems, especially when tested in magnesium sulfate solution, and propose proper laboratory tests for evaluating the sulfate resistance of mortars with various types of binders.
