Strength and Durability Properties of Concrete Containing Pumice and Scoria as Supplementary Cementitious Material

Concrete structures suffer serious deterioration under a corrosive environment. Consequently, the service life of these concrete is decreased and deteriorates combined attack sulphate chlorides. Most studies confined on single deteriorating factor such as only or chloride but current study focused influence natural pumice (NP) scoria (NS) strength performance exposed to chloride. Portland cement (PLC) was replaced with NP NS at substitution level 10%. samples were cured in water for curing period 28 days. Afterwards, specimens immersed 5% sodium (Na2SO4), (NaCl), solutions additional 28, 56, 90 The results compared between mixes control mix (CT) PLC. effects sulphate, chloride, evaluated terms change weight, variation compressive strength, degree damage. Conclusively, application has extraordinary potential be utilized cementitious material increase resistance against aggressive salts.
