The effect of limestone aggregate on the properties of fly ash based geopolymer concrete

The uses of Portland cement give disadvantages to the nature which is by releasing carbon dioxide gas to the air. This situation can cause global warming at the same time contribute to the greenhouse effect. Besides, the production of Portland cement causes depletion of raw material. In order to sol...
