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

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 r...

The use of super- Plasticizer can have an effective role in reducing negative effects MINAB on concrete properties.

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.Jalil ShafaeiSeyed Fazlolah SaghravanibAli TorkiIranian Society of Structrual Engineering (ISSE)articlemortar cementmicro-nano air bubble (minab)super-plasticizermortar compressive strengthsetting timeBridge engineeringTG1-470Building constructionTH1-9745FAJournal of Structural and Construction Engineering, Vol 8, Iss 3, Pp 205-217 (2021)
