According to the Slag Cement Association, some of the quantitative benefits of using slag cement or ground granulated blast furnace slag in concrete include improved workability and finishability, higher compressive and flexural strengths, improved resistance to aggressive chemicals, improved durability and reduced life cycle costs.

Fresh Concrete Properties with Ground Granulated Blast Furnace Slag. ... Tests showed that 40 to 70% of replacement of ordinary Portland cement with GGBFS lead to increase in the rate of bleeding. A higher replacement with GGBFS leads to increase in the bleeding.

May 12, 1998· Cement is made from base metal smelter slag produced by a nickel, copper, lead or zinc smelter. The slag is ground to a size within the range of from about 250 to about 425 mesh to produce ground slag cement, and the ground slag cement is mixed with Type 3 high early strength Portland cement in a ratio of at least about :1 by weight to produce a blended cement.

It is often called slag cement and is used as a cement replacement for portland cement, glass making, concrete block manufacturing, filtration medium, and soil amendment ( 4 ).

In this work, the preliminary study about the use of secondary lead smelting slag (SLSS) as an addition to Portland cement is presented. SLSS is a waste from a Colombian secondary lead .

Slag Cement and Life Cycle Prediction Models What Are Life Cycle Prediction Models? Life cycle prediction models are engineering tools developed from an understanding of concrete performance, gained from basic material research and engineering practice and used to predict the life and establish the cost of a structure, including maintenance and repair.

Question: We heard that the greenish blue discoloration often found on concrete containing slag can be removed with a 3% hydrogen peroxide solution. Our experience suggests that this treatment may lead to scaling of earlyage concrete. We found dilute solutions of vinegar to be effective.

Just like aircooled blast furnace slag, this slag has a hydraulic property and there is no risk of alkaliaggregate reaction. Because of the powerful latent hydraulic property that results from fine grinding, this slag is used in products such as Portland blast furnace slag cement.

aggregate in asphaltic concrete was conducted in January 1991. The test program included extensive characterization of the chemical composition and physical properties of the spent grit. Asphaltic concrete samples were made with 7 percent grit and a bitumen content ranging from to percent (based on the total mixture weight).

Electric Arc Furnace Slag in Concrete Juan M. Manso1; Javier J. Gonzalez2; and Juan A. Polanco3 Abstract: This paper describes the work carried out in laboratory to produce concrete with good properties using oxidizing electric arc furnace (EAF) slag as fine and coarse aggregate.

Heavy concrete is an excellent shielding material most widely used for radiation shielding of gamma rays. It is possible to use lead slag as a partial replacement of aggregates to increase the density of concrete shields. From an environmental point of view, substitution of natural aggregate with lead slag can saves our natural resources and land.

Abstract. The technical properties of cement mortars containing natural fine aggregate that is replaced by lead blast furnace slag at 25 and 35% level were assessed at fixed watertocement (W/C) ratio and at fixed flow table value.
