| Resumo: | This paper reports the results of experimental research on certain engineering properties of a new (portland cement-free) concrete made with alkali-activated fly ash. Laboratory tests were conducted to determine its (bending and compression) mechanical strength, modulus of elasticity, bond strength, and shrinkage. The results show that mortar and concrete made with portland cement-free activated fly ash develop a high mechanical strength in short periods of time, have a moderate modulus of elasticity and bond better to reinforcing steel and shrink much less than ordinary portland cement (OPC) concrete. |
