Sep 30, 2021 Aggregates are the major constituent (ingredient) in concrete, making up 60% to 70% of the volume of concrete. Aggregates influence the workability of plastic concrete and also the durability, strength, thermal properties, and density of hardened concrete. Particle size divides aggregates into two categories fine and coarse. Most fine aggregates are sand and contain particles smaller than 3/8 ...

Concrete Specifications Archinomy

Specifications for construction aggregates have been developed for a variety of construction applications. The most important construction materials specifications for aggregates are for roadway and pavement construction (including hot-mix asphalt, granular base and granular sub-base), and for concrete materials used in buildings, civil engineering structures and infrastructure construction. Keywords Concrete, guidelines, recycled aggregate, specifications. 1 INTRODUCTION The development a national Guide specification document on recycled concrete and masonry aims at providing engineers with product specification information and the tools required for conventional design with graded recycled construction and
