Study of Granulated Blast Furnace Slag as Fine Aggregates in

specimens were moist cured. The test results proved that the compressive strength of concrete mixtures containing GGBS increases as the amount of GGBS increase. After an optimum point of 55% replacement, the addition of GGBS does not improve the compressive strength. The early strength of GGBS concretes was lower

Effect of Glass Powder and GGBS on Strength of Fly Ash Based

strength obtained for concrete having FA and 10% GP was found to be the highest. Hence, it was decided to prepare concrete having FA, 10% GP and different percentages of GGBS to study the effect of GGBS on the strength of geo-polymer concrete. In order to study the tensile strength of concrete having

Utilization (recycling) of iron and steel industry by-product

Oct 19, 2013 · Utilization (recycling) of iron and steel industry by-product (GGBS) in concrete: strength and durability properties. Abstract. Due to exponential growing in urbanization and industrialization, byproducts from industries are becoming an increasing concern for recycling and waste management.

Ground Granulated Blast Furnace Slag GGBS Concrete

GGBS concrete behaves in a similar manner to fly ash concrete and affects the setting time, strength gain and workability of the concrete. GGBS Physical Properties GGBS used in concrete is a byproduct of metallurgical processes, most commonly the blast furnace production of iron from iron ore.


Reason for Development of SCC The main factors for development of Self-Compacting Concrete are to achieve high durable, flow-able, workable and self compacting of concrete and to solve weakness properties of concrete as we know that concrete is a brittle material with low tensile strength, volume stability, low ductility and low strength to ...


grade concrete such as compressive strength, split tensile strength and flexural strength of concrete is discussed. The results are compared with that of the normal concrete Key words: Compressive strength, Fly ash, GGBS, Recycled fine aggregate, Split tensile strength.

Green Concrete: Its Application, Advantages & Disadvantages

The green concrete has less split tensile strength than the ordinary concrete. In the eco-friendly concrete, the cost of the reinforcement increases with the use of stainless steel. A detailed life cycle analysis of green concrete by considering different parameters is must to understand the resultant concrete properties.

How to make concrete stronger and more environmentally

Concrete has shaped the modern world. Other than water, it is the most widely used material on the planet so it's unsurprising that scientists are constantly working to make it safer, stronger and ...

Sustainable Concrete - An Inevitable Need for Present & Future

We need to increase use of classified fly ash by processing fly ash into different categories based on its fineness so that it can contribute effectively in producing very high strength as well as normal strength and durable concrete with lower cement utilization. Recycling of concrete from C&D wastes.


High Strength Concrete using Ground Granulated Blast Furnace Slag (GGBS) Thavasumony D, Thanappan Subash, Sheeba D. Abstract — Concrete is a brittle material when it undergoes heavy loads, cracks will form and to reduce this and improve high strength

Cement & Concrete Composites

strength and durability of the concrete by creating a denser matrix and thereby would increase the service life of the concrete struc-tures. It is well known that the incorporation of FA and GGBS with normal fineness reduces the early strength of concrete, but they have long term advantages, such as improved long-term strength


A concrete mix of M30 is taken as the reference mix. Cement is replaced with GGBS with 0% and 10%.The effect of replacement of coarse aggregate by e-waste material and cement by GGBS on properties of concrete are studied for compressive strength and


construction waste and sugarcane bagasse ash to partially replace basalt stone and quartz sand. Mechanical properties of concrete made with 30% of SBA and 30% of construction waste were similar to the reference concrete. Joint application of SBA and construction waste achieved 93% of compressive strength.

Effect of using selected industrial waste on compressive and

sludge as a source of water in concrete production has insignificant effect on compression strength, while it has a sharp effect on the slump values. K. Pazhani, R. Jeyaraj showed study on durability of high performance concrete with industrial wastes using copper slag and ground granulated blast furnace slag (GGBS).

Regen GGBS - Cement Substitute

What is Regen?Regen Ground Granulated Blast furnace Slag (GGBS) is a cement substitute, manufactured from a by-product of the iron-making industry. Using one tonne of Regen in concrete reduces the embodied CO2 by around 900kg, compared to using one tonne of Portland Cement, and also increases its durability. Regen is more sustainable than other cement substitutes such as Fly Ash.In …
