Analysis of the Influence of Clay Dosage and Curing Age on the Strength of Plastic Concrete
Abstract:
This test is sand coarse aggregate ratio, ratio of water to cementitious material, cement dosage, bentonite dosage, type of sand and type of bentonite in certain cases, studied the influence of clay dosage and curing age on the basic mechanical properties of plastic concrete, it is concluded that the best clay dosage; the clay dosage has a great influence on all the strength of plastic concrete (compressive strength, splitting tensile strength, rupture strength), with the increase of clay dosage and all kinds of strength decreased; when clay dosage is certain, various strengths of plastic concrete are increased with the increase of curing age, curing age has a great influence on various strengths of plastic concrete. If the long curing age (540d) intensity values as the actual strength of plastic concrete, growth rate of strength of 540d long age relative to the 28d age about 120%, this shows that plastic concrete has a higher late strength, plastic concrete curing age longer than concrete curing age.
