Durability of fly ash geopolymer mortars in nitric acid ...

Volume of penetrable pores as determined by mercury intrusion porosimetry was found greater in the specimens with lesser [Na.sub.2]O content 3. Mortar specimens manufactured by activation with alkaline activator of higher alkali content exhibited better performance in nitric acid on the basis of weight loss and retention of compressive strength.

Seven Must-Use Concrete Admixtures (Additives)

One problem associated with using a high range water reducer in concrete is slump loss. High workability concrete containing superplasticizer can be made with a high freeze-thaw resistance, but air content must be increased relative to concrete without superplasticizer.

Rice Husk Ash as Fine Aggregate Sustainable Material for ...

Rice husk ash (RHA) is a by-product of the rice milling industry. Near about 20 million tonnes of RHA is produced annually which creates environmental pollution. Utilization of RHA as a supplementary cementitious material adds sustainability to concrete by reducing CO2 emission of cement production. But, the percentage of utilization of RHA is very less.
