MICROSCOPIC STUDY OF THE CONCRETE / GEOPOLYMER

The geopolymer mixtures applied to the concrete sur-face are summarized in Table 1. In all cases, a clay-based geopolymer was used as a matrix. The content of additives/fillers was selected based on previous experience [11, 15, 23, 26, 27] and with respect to the viscosity and workability of the geopolymer mixture. Materials The materials employed in the experiments are men-tioned below.

Experimental Study of Geopolymer Concrete Resistance to

Geopolymer concrete is well known for its high chemical resistance. Class F fly ash was firstly activated in a highly alkaline sodium silicate environment to obtain Geopolymer, which was further mixed with silica sand and aggregates to make Geopolymer concrete. The resultant Geopolymer concrete developed a compressive strength of 70MPa at age of 28 days, after being initially cured at 70ºC
