PDF Strengthening of Self Compacting Concrete Using Ground

strength at 30% addition of GGBS is 1.74%. Thus, it can be concluded that maximum compressive strength of self compacting concrete with the combination of admixtures (SP+VMA) may be obtained by adding 30% GGBS which is a waste material of Iron industry.

Durability Properties and Microstructure of Ground Granulated

May 20, 2014 · 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.

Study of Properties of Concrete using GGBS and Recycled

GGBS is used to make durable concrete structures in combination with ordinary Portland cement. GGBS concrete has slightly slower strength development at early ages. At 7 days GGBS concretes will have 50 to 60% of its characteristic strength compared. At 28 days GGBS concrete may fully

WASTE PAPER SLUDGE ASH AND GROUND GRANULATED BLAST FURNACE

This paper investigates workability and strength of concrete made with different proportions of waste paper sludge ash (WSA) and ground granulated blast-furnace slag (GGBS) as binder, at two w/b rations: 0,5 and 0,4. Specimens were tested unconfined compressive strength after 1, 7, 28 and 90 days of curing.
