RILEM TC 127-MS: TESTS FOR MASONRY MATERIALS AND STRUCTURES Recommendations
Basically, all masonry units are suitable for tests. Randomly sample 5 masonry units for determining the moisture content. Additionally, for tests with no preload, randomly sample a further 15 masonry units for the construction of the specimens and, for tests with preload, randomly sample a further 15 masonry units per preload value for the construction of the specimens. A minimum of 3 preload ...
متن کاملEFFICIENCY FACTOR OF SUPPLEMENTARY CEMENTITIOUS MATERIALS: A STATE OF ART
The use of supplementary cementing materials is gradually increasing due to technical, economical, and environmental benefits. Supplementary cementitious materials (SCM) are most commonly used in producing ready mixed concrete (RMC). A quantitative understanding of the efficiency of SCMs as a mineral admixture in concrete is essential for its effective utilisation. The performance and effective...
متن کاملBest Practices for Concrete Pavements / Supplementary Cementitious Materials Tech brief
Hydraulic activity refers to a property most familiar when discussing hydraulic cement such as ordinary portland cement (OPC). ASTM C125-15a defines hydraulic cement as “a cement that sets and hardens by chemical reaction with water and is capable of doing so under water.” That is, hydraulic cements, including SCMs that have hydraulic properties, react with water to harden, and that hardening p...
متن کاملFeasibility Tests on Concrete with Very-High-Volume Supplementary Cementitious Materials
The objective of this study is to examine the compressive strength and durability of very high-volume SCM concrete. The prepared 36 concrete specimens were classified into two groups according to their designed 28-day compressive strength. For the high-volume SCM, the FA level was fixed at a weight ratio of 0.4 and the GGBS level varied between the weight ratio of 0.3 and 0.5, which resulted in...
متن کاملUsing Different Methods of Nanofabrication as a New Way to Activate Supplementary Cementitious Materials; a Review
Reducing the consumption of cement with simultaneous utilizing waste materials as cement replacement is preferred for reasons of environmental protection. Blended cements consist of different supplementary cementitious materials (SCMs), such as fly ash, silica fume, Ground Granulated Blast Furnace Slag (GGBFS), natural pozzolans, etc. These materials should be chemically activated to show effec...
