selfcompacting concrete (scc) mix designs demonstrate complexities in their mechanical properties due to natural compounds of the material and the diversity and abundance of factors that affect the properties. In this paper, a set of scc mix designs is made using silica quicksand (as a filler) instead of rock powder with other required materials.

This study presents results on the performance of selfcompacting concrete (SCC) mixtures containing pumice powder as a pozzolan in various proportions. The required superplasticizer dosage, used to obtain the desired initial slump flow, was determined when compared to mixtures containing .
compacting concrete for M30 and M35 Grade Concrete. For best result the percentage of ceramic waste powder will be decided for fresh and harden property of selfcompacting concrete. The project can lead to the use of ceramic waste powder in Self compacting concrete, thus saving landfill and reduce CO2 emission by the use of less cement.
composition of Self Compacting Concrete is same of normal concrete, that is, cement, fine and coarse aggregates, water, mineral and chemical admixtures. The notable difference of SCC from normal concrete is that the SCC contained a high dosage of powder, as well as a high dosage of high range water reducing agents (Super
compacting concrete for M30 and M35 Grade Concrete. For best result the percentage of ceramic waste powder will be decided for fresh and harden property of selfcompacting concrete. The project can lead to the use of ceramic waste powder in Self compacting concrete, thus saving landfill and reduce CO2 emission by the use of less cement.
Selfconsolidating concrete or selfcompacting concrete (commonly abbreviated to SCC) is a concrete mix which has a low yield stress, high deformability, good segregation resistance (prevents separation of particles in the mix), and moderate viscosity (necessary to ensure uniform suspension of solid particles during transportation, placement (without external compaction), .
and can increase the workability properties of self compacting concrete mix. All self compacting concrete mixes showed acceptable slump flow value of 650768 mm that posses a good deformability. The self compacting concrete mixes gave values within the range of to in Lbox test.
In this paper the properties of Self Compacting Concrete (SCC) was investigated using white cement and lime stone powder as fine aggregate instead of sand. All mixtures were proportioned with constant amount of (cement, lime stone powder, coarse
This paper reports on an experimental investigation using either rubber aggregates or steel fibres recycled from waste tires in the production of selfconsolidating concrete composite (SCCC). Ten mixes are designed, one of them is the reference concrete. The natural aggregates are substituted by rubber particles by volume at 5, 10, 15, 20 and 30%.
selfcompacting concrete containing water binder ratios of and In addition the concrete is treated with different dosage of superplasticizer based on carboxylic with flyash. To evaluate the passing ability of the self compacting concrete, slump flow test, Vfunnel test and L .
Influence of water/powder ratio on strength properties of selfcompacting concrete containing coal fly ash and bottom ash
Aug 01, 2011· The development of selfcompacting concrete is considered as a milestone achievement in concrete technology due to several advantages. In order to be selfcompactable the fresh concrete must show high fluidity besides good cohesiveness. ... It is evident that the paste containing the rubble powder (Cem + RP) show the maximum yield stress value ...
selfcompacting concrete containing water binder ratios of and In addition the concrete is treated with different dosage of superplasticizer based on carboxylic with flyash. To evaluate the passing ability of the self compacting concrete, slump flow test, Vfunnel test and Lbox test had been conducted.
Studies to develop selfcompacting concrete, including a fundamental study on the workability of concrete, were carried out by Ozawa and Maekawa at the University of Tokyo. Definition . Selfcompacting concrete (SCC) is a concrete type, which has considerable liquidity feature and ability to emplace by its own weight.
Jul 07, 2015· Figure 2Masonry model and maximum values of the mortarbrick bond strength. SelfCompacting Concrete Containing Rubble Powder Finally, a third experimental step was carried out concerning selfcompacting concrete by using the dust produced during the rubble processing as a filler for manufacturing selfcompacting concrete.
On the other hand, Selfcompacting concrete, a recent innovation in concrete technology is being regarded as one of the most promising developments in the construction industry due to numerous advantages of it over conventional concrete. Selfconsolidating concrete, as the name indicates, is a type of concrete that does not
mechanical properties of self compacting concrete with different types of filler such as limestone powder, pigment and hydrated investigated mechanical properties were compressive strength, splitting tensile strength, flexural strength, modulus of elasticity, the ultrasonic pulse velocity and schmidt rebound hammer tests.

Oshogbunu5 Abstract: This paper examines the effect of combined bamboo fibers and limestone powder used as filler material on the fresh, hardened and microstructural properties of selfcompacting concrete ...
The sample containing 10 % Rice Husk Ash, 10% Waste Glass Powder and 39% micro silica produced worst workability as it decreased the workability up to 5 % of controlled concrete. The results for axial compressive strength shows that the addition of 15% Rice Husk Ash (RHA) and 39% of Fly Ash (FA) in concrete leads to the improvement of ...
1. Introduction. Selfcompacting concrete is a special type of concrete that flows under its weight, compacts under its weight and can occupy all the spaces of the formwork without any need for vibration and, at the same time, cohesive enough to be handled without segregation or bleeding, .Conventional concrete is usually placed and vibrated in the formwork, but selfcompacting concrete is ...
