The best woodcement ratio was 3:1, and adding 10% of gypsum as partial substitution of cement improves the compression strength with % CS = N/mm 2, while for control specimens CS = N/mm 2. However, adding more than 20% gypsum effected the compression strength negatively.
PolyLoc is a polyvinyl acetate (PVA) based bonder or admixture for cementitious or gypsum plaster products. PolyLoc can be used in bonding new cementbased or gypsumbased products to a variety of existing, properly prepared substrates and as an admixture to increase tensile, bond, and flexural strength of approved products.
The quality of the aerated concrete strongly depends on the chemical composition of the raw materials, as well as the process of the hydrothermal reaction during autoclaving. Due to the variable chemical composition of fly ashes, it is necessary to identify the effect of each ion on the formation of the microstructure of aerated concrete. This paper examines the process of formation of ...
