This paper demonstrates the use of waste foundry sand as a partial replacement by fine aggregate and slag is as coarse aggregate in concrete. An experimental investigation is carried out on concrete containing waste foundry sand in the range of 0%, 20 %, 40% by weight and slag is fully replaced () for M25 grade concrete (OPC).

Tool can compare impact of mix designs on project . Compares custom mixes to benchmark building . Reduces environmental impact of concrete mixtures . In Conclusion: Slag Cement .
Properties And Effects Of Copper Slag In Concrete 50 CONCLUSIONS Conclusions: 1. As the percentage of copper slag increases workability increases. 2. Maximum Compressive strength of concrete increased by 34 % at 20% replacement of fine aggregate, and up to 80% replacement,concrete gain more strength than normal concrete
During an educational session on Wed., March 28, the Slag Cement Association (SCA) presented the 2017 Project of the Year Awards. Each project was selected by the SCA''s Technical Marketing Committee because of its exemplary and innovative uses of slag cement in concrete mix design.
Apr 17, 2017· I had practically used PPC cement in almost all projects. I didn''t find any problem. Portland Slag Cement (PSC) Portland Slag Cement (PSC) is manufactured by either intergrinding in the Portland cement clinker, Gypsum Granulated Slag or blendin...
Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial byproduct of an iron blast furnace.
Feb 07, 2020· Slag cement has actually been used in concrete projects in the United States for over a century. Its earliest use was documented in 1774, when it was combined with slaked lime and used as a cement was first used commercially in Germany in the 1860s, and it was such a success that engineers in 1889 decided to build the Paris underground metro using slaglime cement.
Concrete made with GGBS cement sets more slowly than concrete made with ordinary Portland cement, depending on the amount of GGBS in the cement mix, but also continues to gain strength over a longer period leading to improved overall durability and life expectancy. Silica fume. Silica fume is a byproduct from the manufacture of silicon.
So, the present study focuses to replace sand by welding slag (WS) and furnace slag (FS) in the production of concrete. Properties of aggregates and slag were studied in detail. M25 concrete was designed for various percentages of slag, and compressive strength of concrete was found out.
Aug 01, 2017· This paper presents the mechanical behavior of concrete mixes containing Used Foundry Sand (UFS) as partial replacement for fine aggregates. Used Foundry Sand is a byproduct from ferrous and non ...
This paper presents a laboratory investigation on optimum level of Fly ash and Ground Granulated Blast Furnace Slag (GGBS) as a partial replacement of cement to study the strength characteristics of concrete. Portland cement was partially replaced by
Sidney M. Levy, in Construction Calculations Manual, 2012. Ground Granulated BlastFurnace Slag. Although portland blastfurnace slag cement, which is made by intergrinding the granulated slag with portland cement clinker (blended cement), has been used for more than 60 years, the use of separately ground slag combined with portland cement at the mixer as a mineral admixture did not ...
Sep 13, 2014· in the video one can see use of crushed sand in making concrete mix for construction purpose. this saves lot of river sand. strength is extremely good compare to concrete using river sand.
Mechanical Properties Of Concrete Using Steel Slag Aggregate Page | 9 improvement in compressive strength, split tensile and flexure strength over control mixes by 4 to 8 %. The replacement of 100 % slag aggregate (coarse) increased concrete density by about 5 to 7 %
of beneficial utilization of used foundry sand in concrete as a partial replacement of regular sand by studying properties of both fresh and hardened concrete. An extensive literature search was undertaken and tests were conducted on byproduct samples to determine their physical properties to evaluate the possible uses (Naik et al. 1991, 1992).
In this project our main objective is to study the influence of partial replacement of cement with marble powder, and to compare it with the compressive and tensile strength of ordinary M20 concrete. We are also trying to find the percentage of marble powder replaced in concrete that makes the strength of the concrete maximum.
Groundgranulated blastfurnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a byproduct of iron and steelmaking) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.
Experimental Study on Partial Replacement of Cement by Flyash and GGBS Syed Asif Ali1 Professor Shaik Abdull2 ... Furnace Slag (GGBS) as a partial replacement of cement to study the strength characteristics of concrete. Portland ... Potable water is used for mixing concrete. H. Casting and Curing of Control Specimen:
As a byproduct of existing industrial processes, GGBS is even more sustainable than many other cement substitutes such as fly ash. Our products conform to BS EN 151671. This is the British standard for the use of Ground Granulated Blast furnace Slag in concrete, mortar and grout. GGBS counts fully towards the cement content of concrete mixes.

ferrochrome slag partially to the cement in concrete will not only conserve the cement but also reduces the environmental impacts of it. The replacement of ferrochrome slag partially to the cement in concrete minimizes total cost of concrete FUTURE SCOPE: The project was carried out with partial replacement of cement using Ferrochrome Slag.
and modulus of elasticity of steel slag concrete was comparable with those of dolomite based mixture up to a temperature of 600°C beyond which it decreases. CaOQurishee et al. [5] studied the strength of concrete using induction furnace slag as a replacement for its coarse aggregates and compared it with concrete with stone chips.
