of steel slag as partial replacement of coarse aggregate in concrete is economical for the better strength and workability it imparts up to 75% replacement level. It is found that increase in replacement level of steel slag above 75% decreases the strength and workability of concrete.
the coconut fibre ash, which in turn was used as a pozzolana in partial replacement of cement in concrete production. Concrete cubes were produced using various replacement levels of 0, 10, 30, 50, 70 and 90 percent of ordinary Portland cement (OPC) with CFA. A total of 50 cubes were
EFFECTIVE UTILIZATION OF RICE HUSK ASH BY PARTIAL REPLACEMENT OF CEMENT G M INSTITUTE OF TECHNOLOGY, DAVANAGERE 577006 Page 8 phase on the alkalinity of the pore water which could only attain the high pH after some days of hydration. Pozzolan can partially replace cement in mortar or concrete mix without affecting strength development.
cement replacement in concrete, or as raw material has the dual benefit of eliminating the cost of disposal and lowering the cost of the concrete. The use of copper slag in the concrete industry as a replacement for cement can have the benefit of reducing the costs of .
Based on overall observations it could be recommended that slag could be utilized as coarse aggregate in concrete production either as partial or full replacement of granite aggregate. Keywords: granite, iron and steel slag, Xray diffract meter (XRD), scanning electron .
of this waste as a replacement of cement. The cement replacement by stainless steel slag waste provides an increased in compressive and flexural strength for 10% substitution respect to the control. For stainless steel slag waste crushed we are observed better results. For mortars manufactured with this percentage, the retractions
The slump increases with the increase in the percentage of Basic oxygen furnace slag in the concrete and reaches a maximum of 72 mm at 35% replacement of sand with basic oxygen furnace slag [79], when compared with control mix of concrete (Table 10 and Figures 8 and 9).
Prof. Warudkar Abhijit A., Mr. Nigade "Technical Assessment on Performance of Partial Replacement of Coarse Aggregate by Steel Slag in Concrete", International Journal of Engineering Trends and Technology (IJETT), V30(1),3741 December 2015. ISSN:. published by seventh sense research group. Abstract Road Construction is an activity in which natural .
Also, furnace slag can be used as coarse aggregate for making concrete as well as aggregate in asphalt paving roads [Dieu and Lunagaira 2015]. Flue dust can be used in many industrial products as the source of carbon and zinc and also in fertilizer production [Yi et al 2012].
Recycling. Pelletized blast furnace slag has been used as lightweight aggregate and for cement manufacture. ed slag has been used as a lightweight aggregate for Portland cement concrete. Granulated blast furnace slag has been used as a raw material for cement production and as an aggregate and insulating material.
Similarly, 5%, 10%, 15%, 20% 25% GGBS Replacement with cement and 10%, 20%, 30% 40% replacement steel slag with sand, It was found to be compressive strength of .
Use of Iron Slag as Partial Replacement of Sand to Concrete Chetan Khajuria¹, Assistant Professor, Civil Engineering Department. ... The results confirm that the use of iron slag ... using slag replacement." Cement and Concrete Vol. 30 pp 465472. [2] A Guide to the Use of Iron and Steel Slag in Roads.
partial replacement of steel slag in concrete. 250tph river stone crushing line in Chile. 200tph granite crushing line in Cameroon. 250tph limestone crushing line in Kenya. 250tph granite crushing line in South Africa. 120tph granite crushing line in Zimbabwe. 400tph crushing plant in Guinea.
to the use of cement, its partial replacement by other materials is proposed. At this point, the idea of valorization of existing waste in the industry itself becomes important. Steel slag is a byproduct of steel manufacturing, which is obtained by the chemical reactions that take place in .
So, the concrete with partial replacement of CA and FA by steel slag shows better resistance to Hcl than to H 2 SO 4 . ξ The penetration of chloride ion in rapid chloride penetrability is low for conventional concrete and 40% fine aggregate replacement concrete.
granulated blast furnace slag is better replacement of cement than various other alternatives. The rateof strength gain in slag replaced concrete is slow in early stages but with proper curing the strength goes on increasing tremendously. The compressive strength decreases when the cement replacement is more than 50%. Use of slag or
Chetan Khajuria, Rafat Siddsique1, 2014,Use of Iron Slag as Partial Replacement of Sand to slag is one of the industrial byproduct from the iron and steel making this paper investigation, the compressive strength of the iron slag concrete was studied. The .
Jun 17, 2017· Various mix combinations with a partial replacement of 10%, 20%, 30% and 40% by the weight of cement by GGBS was taken and %, 1% and % steel fiber of hooked end type of aspect ratio 5060 were used. The test results show that the partial replacement of cement by both GGBS and steel fiber has an increase in the strength of concrete.
Compressive strength of blast furnace slag concrete with different dosage of slag was studied as a partial replacement of cement. From the experimental investigations, it has been observed that, the optimum replacement of Ground Granulated Blast Furnace Slag Powder to cement without changing much the compressive strength is 15%.
when exposed to acid and sulphate attacks. Steel Slag powder as partial substitute for cement and ROBO sand as complete alternative for natural sand are combined mostly on basis of the criteria of durability properties and costing qualities. Not only these properties, pollution in environment can also be lowered upto some extent due to the fact that
steel slag as an alternative material for aggregate in concrete. This work is a study of physical properties and strength behaviour of concrete by partially replacing cement with Calcium Bentonite powder and fine aggregate with steel slag. Concrete specimens prepared by partially replacing cement with different percentage of Calcium
of 20 mm was used and GGBS was used as a partial replacement of cement for various volume ratio. The properties of these materials were determined by conducting test as per IS code. The test results are presented in Table 1. STEEL FIBER Adding steel fibre to a plain concrete has no effect on its precracking behaviour but does substantially
