Fibre-reinforced decorative composite: the effects of composition on the strength
Journal Title: Вісник Одеської державної академії будівництва та архітектури - Year 2018, Vol 1, Issue 73
Abstract
The paper continues to present the results of the study aimed at getting high performance decorative concrete. To the previously presented analysis of the influence of the composition on the growth process of the plastic strength of concrete mix, the results of consideration of the compressive and flexural strength of the concretes in the dried and water-saturated states have been added. The effects of fine zeolite (active mineral additive), quantity of fine sand in mixture with more coarse one, dosages of superplasticiser and alkali resistant glass fibres of 6 and 12 mm length on the strength have been evaluated with the 2-order experimental-statistical models. The models have been built on the data obtained for 27 compositions, in accordance with 5-factor design of experiment. The visualisation of the local fields of concrete strength in coordinates of the part of factors, changing when the values of other factors change, helps to analyse the individual and synergetic effects of the components and to outline the next research tasks.
