Disperse reinforced cast concrete based on mechanically activated cement-ash binder
Journal Title: Вісник Одеської державної академії будівництва та архітектури - Year 2017, Vol 1, Issue 68
Abstract
The article deals with the influence of the dosage of fly ash in portland cement in the presence of superplasticizer C-3 and basalt fiber on the strength of cast concrete. It is determined that concrete strength is reduced by an average of 2.5-4.5% for every 10% of the dosage of fly ash. The mechanic activation of cement-ash binder increases the strength of cast concrete compared with the control specimen on average of 30-35%, which allows to increase the dosage of fly ash in concrete by 15-20%. It was found that the presence of 80% of the ash in the binder when it is being mechanically activated in the presence of superplasticizer C-3 allows to obtain cast concretes with strength of 15-22MPa. Insignificant influence of the dosage of basalt fiber on the strength increase (up to 10%) of the cast concrete was stated.
