Strength predictions03 October 2018, Published under Cement NewsA prediction of strength in concrete can be made through a range of methods and with numerous variables. To facilitate this, Arthur Harrisson examines the key factors that control strength development in concrete. Figure 1: cement 28-day strengths Various methods have been developed to predict the strength that a concrete may reach with a particular combination of cement, supplementary cementitious materials (SCMs), aggregate, admixture and even water. The variables are numerous... |
Graphene may have commercial use as concrete additive14 September 2018, Published under Cement NewsZenyatta Centures Ltd's research with the University of Toronto into cement strength when using small quantities of graphene from Albany Graphite has led to some startling results. Using just 0.02 per cent of the graphene product when combined with cement saw compressive strength of cured cement paste increase by 39 per cent, reports Junior Mining Network. Professor Deman Panesar, University of Toronto Department of Civil & Mineral Engineering, said, "This encouraging preliminary result ... |
Self-healing concrete10 September 2018, Published under Cement NewsThe formation of cracks in concrete is a common occurrence and in many cases is not regarded as a major issue. However, in some circumstances they may pose a threat to a concrete structure if its purpose is to prevent the movement of water or if there is a risk of the ingress of deleterious materials. Research is underway in a number of locations to investigate ways of encouraging healing of the cracks without major intervention. Figure 1: microcracks in concrete (cracks are up to 0.0... |
