Slag Cement Association

Slag cement is a recovered byproduct of the iron manufacturing process and can be used to replace a portion of portland cement in concrete mix design. The use of slag cement has demonstrated long-term performance enhancements allowing designers to reduce the environmental footprint of concrete while ensuring improved performance and increased durability.

Experimental study on the mechanical and durability ...

Replacement of cement by GP was from 5% to 45% in step of 5% and the GGBS with range of replacement from 45% to 5% in step of 5% respectively. In total, ten different combinations of mixes were studied at three different ages of concrete namely 3, 7 and 28 days of concrete.

replacement of GGBS with cement.They also concluded that the maximum split tensile strength is obtained at the 20 % replacement level of GGBS with cement. B. Vinayak Awasare, Prof. M. V. Nagendra In this paper they have studied on the GGBS Blended cement concretes for M 20 mix design the compressive strength and flexure strength are determined with addition n of 20,30,50.% of GGBS …

All About GGBS

The replacement ratio of GGBS has significant impact on the strength development of concrete; hence, the user should determine the best range of replacement ratio through experiment, in accordance to the design and construction requirements.

Coal Fly Ash - User Guideline - Portland Cement Concrete ...

Structural design procedures for concrete pavements containing fly ash are no different than design procedures for conventional concrete pavements. The procedures are based to a great extent on the design strength of the concrete mix, usually determined by testing after moist curing for 28 days.

Comparative Study On Stabilization of Soil With Ground ...

conducted in accordance with the standard procedures for different combinations of soil and additives. Soil stabilization is any process which improves the physical properties of soil, such as increasing shear strength, bearing capacity etc. which can be done by use of controlled compaction or addition of suitable admixtures like cement, lime and waste materials like fly ash, GGBS, rice husk ...

Durability Properties and Microstructure of Ground ...

Ground granulated blast-furnace slag (GGBS) is a green construction material used to produce durable concrete. The secondary pozzolanic reactions can result in reduced pore connectivity; therefore, replacing partial amount of Portland cement (PC) with GGBS can significantly reduce the risk of sulfate attack, alkali–silica reactions and chloride penetration. However, it may also reduce the ...

CONCRETE Optimizing the Use of Fly Ash in Concrete

For the purposes of this document the replacement levels shown in Table 1 will be used to represent low, moderate, high and very high levels of fly ash. By: Michael Thomas, Ph.D., P.Eng., Professor of Civil Engineering, University of New Brunswick Figure 1. Fly ash, a powder resembling cement, has been used in concrete since the 1930s. (IMG12190) Table 1. Dosage Levels of Fly Ash Level of Fly ...

A Review on Ground Granulated Blast-Furnace Slag as a ...

partial replacement of cement with GGBS. The Blast-Furnace slag is a by-product of the iron manufacturing industry. Iron ore, coke and limestone are fed into the furnace and the resulting molten slag floats above the molten iron at a temperature of about 1500 0C to 1600 0C. The molten slag has a composition of about 30% to 40% SiO2 and about 40% CaO, which is nearly similar to the chemical ...

Ground granulated blast-furnace slag - Wikipedia

GGBS cement can be added to concrete in the concrete manufacturer's batching plant, along with Portland cement, aggregates and water. The normal ratios of aggregates and water to cementitious material in the mix remain unchanged. GGBS is used as a direct replacement for Portland cement, on a one-to-one basis by weight. Replacement levels for GGBS vary from 30% to up to 85%. Typically 40 …
