Properties of Fibre Reinforced Concrete Using Recycled

Concrete is used more than any other man-made material in the world. Concrete like other engineering materials needs to be designed for properties like strength, durability and workability. Concrete mix design is the science of deciding relative proportions of ingredients of concrete, to achieve the desired properties of concrete. Use of

Mix Design for Pervious Recycled Aggregate Concrete

27/11/2012· In the process of mix design of pervious concrete with either natural aggregate or recycled concrete aggregate, Fig. 11 could be used to obtain the void content needed for trial mixes to satisfy the specification requirement for water permeability and compressive strength of concrete. Once the void content is known, simple mathematical approach

Mix design procedure for recycled aggregate concrete

Mix design parameters thus obtained, enable RAC to attain the desired and designed target strength without attempting any trial mixes. The suggested modified procedure, however, demands 10% more cement which is considered quite reasonable and acceptable in view of the inferior quality of recycled aggregate.
