This document provides an introduction to self-compacting concrete (SCC). SCC is concrete that can be placed and consolidated under its own weight without vibration. It was developed in Japan in the late 1980s to address issues with adequate compaction. The key properties of SCC are high flowability and good cohesiveness. These properties allow SCC to fill forms and pass through reinforced areas without segregation or honeycombing. SCC offers advantages over traditional vibrated concrete such as faster construction, improved durability, better surface finish, and a safer working environment by eliminating vibration. While SCC provides benefits, it also has a higher material cost due to increased binder and chemical admixture contents required.
Analysis of Admixtures and Their Effects of Silica Fumes, Metakaolin and PFA...
This paper presents a review of the properties of fresh concrete including workability, heat
of hydration, setting time, bleeding, and reactivity by using mineral admixtures fly ash (FA), silica
fume (SF), ground granulated blast furnace slag (GGBS), metakaolin (MK), and rice husk ash (RHA).
Comparison of normal and high strength concrete in which cement has been partially supplemented
by mineral admixture has been considered. It has been concluded that mineral admixtures may be
categorized into two groups: chemically active mineral admixtures and microfiller mineral
admixtures. Chemically active mineral admixtures decrease workability and setting time of concrete
but increase the heat of hydration and reactivity. On the other hand, micro filler mineral admixtures
increase workability and setting time of concrete but decrease the heat of hydration and reactivity. In
general, small particle size and higher specific surface area of mineral admixture are favourable to
produce highly dense and impermeable concrete; however, they cause low workability and demand
more water which may be offset by adding effective super plasticizer.
Admixtures
This document provides a summary of admixtures used in concrete. It defines admixtures as organic or inorganic materials added in small quantities to modify the properties of mortar. The main types of admixtures discussed are accelerators, retarders, plasticizers, super plasticizers, and air entraining admixtures. Accelerators increase the speed of setting and hardening while retarders decrease setting time. Plasticizers and super plasticizers increase workability and decrease water content. Air entraining admixtures produce small air bubbles that act as ball bearings and modify concrete properties.
High strength pdf.pdf
This document summarizes a project report on high strength (M70) and high performance concrete. It lists the project team members and their institution. It then provides details on the properties, methods to achieve, parameters, and material selection for high performance concrete. The document discusses the work done on mix design, laboratory tests, mix preparation, test results and conclusions for M70 concrete.
Admixtures of Concrete
This document provides an introduction to admixtures used in concrete. It defines admixtures as materials other than cement, water, and aggregate that are added to concrete batches. Admixtures are used to modify the properties of ordinary concrete for different situations. The document then discusses the history of admixtures, why they are used, their functions, and classifications. It notes that admixtures can be used to modify properties of fresh and hardened concrete like workability, strength, shrinkage, and curing. The main types of chemical admixtures are plasticizers, retarders, accelerators, and air-entraining admixtures. Mineral admixtures include cementitious materials like fly ash and slag.
BT 1: Concrete and Admixtures
The document discusses the history and composition of concrete. It explains that modern concrete has greater compressive and tensile strength than ancient Roman concrete due to the use of Portland cement and steel reinforcement. The document also outlines different concrete mixtures based on proportion ratios and their recommended uses. It provides methods for calculating concrete needs and differentiates between concrete, cement, grout, and plaster.
Influence of chemical admixtures on density and slump loss of concrete
This document summarizes a study on the influence of chemical admixtures on the density and slump loss of concrete. [1] Plasticizers and super plasticizers were found to improve workability at a constant water-cement ratio and increase density at a reduced ratio. [2] However, slump loss was also observed to increase with the use of admixtures and at higher dosage levels. [3] The study concluded that admixtures can effectively reduce the water-cement ratio needed for a given slump and increase the density and strength of concrete.
