CONCRETE UNDER DIFFERENT SP60 DOSE AND CURING CONDITIONS
Concrete is a product mainly made from cement, aggregates, water and an additional important material is called Admixtures. Superplasticizer is one of the types of admixtures and attention has been given to the use of superplasticizers to enhance the performance of concrete. Such efforts have increased in Ethiopia and superplasticizer designated as SP60 is currently produced and mainly used in many construction activities. The present work is aimed at studying on the behavior of plain concrete using different dosages of SP60 under different curing conditions for concrete grade C-30 and at constant water cement ratio of 0.45. Experimental tests on 135 standard samples for concrete grade C-30 are carried out to evaluate the effect of the superplasticizer on concrete compressive, splitting tensile and flexural strength under different curing conditions and at an ambient temperature and humidity of 20.1°c and 73% respectively. The optimum dosage of SP60 has been obtained for each strength test. It is observed that concrete cured in water for 28 days showed maximum compression and tensile strength with the addition of 1.5% SP60 and maximum flexural strength at 1% for curing condition (CC1).
