Read MoreConcrete produced using the type i mixture achieved the design strength of 42 mpa at the age of 28 days regardless of curing history, whereas the 28-day compressive strength of concrete of the type ii mixture, except for concrete cured under the hot temperature condition, was slightly lower than the design strength of 65 mpa, as listed in table 3.
Read MoreCompressive strength of concrete cube test provides an idea about all the characteristics of concrete.By this single test one judge that whether concreting has been done properly or not.Concrete compressive strength for general construction varies from 15 mpa 2200 psi to 30 mpa 4400 psi and higher in commercial and industrial structures.
Read MoreThat the moisture content in concrete does have a significant effect on the compressive strength of concrete, but has a much lesser effect on the split tensile strength.As the specimen degrees of saturation increased, the compressive strength fell.However, at nearly saturated condition, an increase in compressive strength can be found.
Read MoreConcrete is a common material used in the nigerian building industry.It is obtained by mixing cementitious materials, water, fine and coarse aggregates and sometimes admixtures in required proportions.Admixtures are added to concrete to modify its properties so as to make it more suitable for any situation.In recent times, building collapse in nigeria has been a source of concern.
Read MoreThe strength of concrete is measured by means of cube compressive strength.However, the actual structural members are not equal in size i.E.The height base area ratio is much higher than the cube on which compressive strength test is conducted.
