Title

Experimental Assessment of Using Micro-Non Air Bubble (MINAB) and Super-Plasticizer on Setting Time and Compressive Strength of Cement Mortar

Pages

  205-217

Abstract

 One of the latest innovations in nano-technology is the use of Micro-nano air bubbles ((MINAB)) as a substitute for water in concrete. Using (MINAB) as a substitute for water used in concrete can be used to improve the properties of concrete. The use of Super-plasticizer can have an effective role in reducing negative effects (MINAB) on concrete properties. In this study, to investigate the effects of (MINAB) with water in concrete in the presence of different Super-plasticizer percentages, the effect of (MINAB) on the Setting time, cement mortar flow and compressive strength of cement mortar is investigated. For this purpose, 16 samples of VICT needles, 48 samples of cement mortar and 16 samples of cement mortar flow were used to check the curing time, compressive strength and cement flow with different percentages of Super-plasticizer (0. 5, 0. 9 and 1. 4) were tested in the presence and absence of (MINAB). The results showed that the compressive strength of cement mortar with (MINAB) increased by 16 and 7%, relative to water at 7 and 28 days respectively. The compressive strength of cement mortar with (MINAB) has increased in presence of Super-plasticizer in comparison to cement mortar with water in presence of Super-plasticizer at the age of 7 and 28 days, with the highest resistance in 0. 5% Super-plasticizer, which increased by 21% at 7 days and increased by 10% at the age of 28.
