Abstract

In the present paper, COMPRESSIVE STRENGTH of cement mortar was investigated through two cases: case I in which just nano-clay (Nano clayto cement proportion equal to 3% and %5) is included, and case II in which both nano-clay and FLY ASH were considered (with the same values for NANO CLAY as case I, and with FLY ASH to cement proportion equal to 15%). Gradual interaction of FLY ASH with calcium hydroxide and alkalins resulted from cement hydration process, produces more C-S-H, spreading through concrete substructure free spaces. Results indicated that, all samples which contain nano-clay are denser than the reference sample. Adding FLY ASH andnano-clay have resulted in decreasing short term period (relating to three and seven days age) COMPRESSIVE STRENGTH of cement mortar. The 28 dayage COMPRESSIVE STRENGTH of samples of case I, showed a dramatic increaseabout 27.2% for proportion value equal to 3%, and a considerable increase about 15.1%, for proportion value of equal to 5%. Results, also indicated a considerable increase in the 90 day age COMPRESSIVE STRENGTH that was about 28.4% and 22.4% respectively relating to two proportion values, 3%and 5%. The 28 day age COMPRESSIVE STRENGTH of samples of case I increased about 1.6% and 4.5% respectively, relating to two values of Nano-clay to cement proportion equal to 3% and 5%. The 90 day age COMPRESSIVE STRENGTH of samples of case II, showed an increase about 10%and 16% respectively, relating to two values of nano-clay to cement proportion equal to 3% and 5%.
