Experimental investigation and prediction of compressive strength of ultra- high performance concrete containing supplementary cementitious materials
Ultra-high-performance concrete (UHPC) has superior mechanical properties and durability to normal strength concrete. However, the high amount of cement, high environmental impact and initial cost are regarded as disadvantages, restricting its wider application. Incorporation of supplementary cementitious materials (SCMs) in UHPC is an effective way to reduce the amount of cement needed while c...
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 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 کاملDurability of Mortar Incorporating Ferronickel Slag Aggregate and Supplementary Cementitious Materials Subjected to Wet–Dry Cycles
This paper presents the strength and durability of cement mortars using 0–100% ferronickel slag (FNS) as replacement of natural sand and 30% fly ash or ground granulated blast furnace slag (GGBFS) as cement replacement. The maximum mortar compressive strength was achieved with 50% sand replacement by FNS. Durability was evaluated by the changes in compressive strength and mass of mortar specime...
متن کاملBleeding of Fresh Concrete Containing Cement Supplementary Materials
Plastic cracking of concrete such as plastic settlement and plastic shrinkage cracking is directly related to the bleeding of concrete, which is a natural time-dependent process in a fresh concrete mix. A portion of the mixing water together with very fine materials finds its way to the surface of the concrete during this process. The rapid rate of initial bleeding slows down with the elapsed t...
