Abstract
To investigate experimentally, the behavior of exterior beam-column joint and strength characteristics of Self Compacting Concrete (SCC) containing Viscosity Modifying Admixture (VMA), and Ground Granulated Blast Furnace Slag (GGBFS). Since there is no standard method of mix design is available for SCC. Hence mix design was arrived as per the rules of European Federation of National Associations Representing for Concrete (EFNARC). Marsh cone test was used to find the saturation of various kind of cements by adding the dosage of super plasticizer accordingly. In this investigation SCC was made by usual ingredients such as cement, fine aggregate, coarse aggregate, water and ground granulated blast furnace slag at various replacement levels (10%, 20%, 30%, 40%, and 50%), with that the Super Plasticizer (Glenium B233) and viscosity modifying agent (Glenium Stream 2) was used in appropriate amount for achieving the better flow in the concrete. The experiments were carried out by maintaining a constant water-powder ratio of 0.45. At various replacement levels the performance of freshly prepared SCC is checked by conducting tests such as slump flow, T50 slump flow, U-tube, L-box and V-funnel tests. Mechanical characteristics like Compressive, Split-tensile and Flexural strength examined. Also, the durability study for SCC after 28, 56 and 90 days curing was done by conducting a number of the tests like saturated water absorption, porosity, carbonation depth and alkalinity measurement
Highlights
Concrete is that the high wide utilized material in innovation development so significant thought is attempted for upgrading the properties of cement regarding quality, strength boundaries
For 30 % Ground Granulated Blast Furnace Slag (GGBFS) substitution levels, the new properties explicit were magnificent as related with 10% percent, 20%, 40% and 50% GGBFS replacement if increasing the GGBFS replacement it can be a stronger effective concrete in self-compacting concrete
The Glenium Stream two having 0.082 with no need a % of 30 minutes GGBFS having higher fluidity and viscosity of the glue is managed and composed by cautious choice and proportioning of the concrete and augmentations, by restricting the water/powder proportion and afterward by expansion of super plasticiser and a thickness changing admixture overseeing these instruments of Selfcompacting concrete (SCC), their similarity and cooperation is significant to accomplishing great filling capacity, passing capacity and protection from segregation.. 3
Summary
Concrete is that the high wide utilized material in innovation development so significant thought is attempted for upgrading the properties of cement regarding quality, strength boundaries. With a quick increment and a much bigger interest for lodging and foundation, supplemented by ongoing improvements in innovation, as multi celebrated structures and long range spans, bigger compressive quality cement was basic. When these mineral admixtures top off a piece of the pc, the estimation of SCC will be decreased prominently if the mineral admixtures are squander or mechanical result. Selfcompacting concrete (SCC) is a creative concrete that doesn't include any vibration for putting and compaction It will flow underneath its own weight, entire filling formwork and achieving full compaction, even within the presence of clogged reinforcement. Self-compacting concrete suggests an expedient rate of concrete arrangement, with quicker construction times and simple flow across clogged reinforcement
