C. D. Gribble writes: I read the technical note by J. C. Bullas with interest. He discusses the value of K used to estimate the value of force (in kN) which must be applied to a sample of aggregate to obtain ten per cent fines in the expression: Force (kN) = K /AIV. The reduction he suggests in the value of K from 4000 to 2800 is based upon samples of crushed rock aggregates, i.e. all the ...

This part of BS 812 describes methods for the determination of the ten per cent fines value (TFV) of aggregates which give a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Two procedures are described, one in which the aggregate is tested in a dry condition and the other in a soaked condition. The methods are applicable to both weak ...

Compressive strength of Concrete and its importance:- As we all know that concrete is a mixture of sand, cement, and aggregate . The strength of the concrete depends upon many factors like individual compressive strength of its constituents (Cement, Sand, aggregate), quality of materials used, air entrainment mix proportions, water-cement ratio, curing methods and temperature effects.
