The effect of using granite dust as a component of

2020-12-1  Replacing sand with disperse granite dust can significantly affect the porosity, resulting in increased density of concrete. Photos of the microstructure of cement paste with granite dust obtained by scanning microscopy indicate that the small particles act as center of crystallization, i.e. accelerate the initial stage of chemical curing.

Palm kernel shell concrete (PKSC) is concrete containing cement, sand and palm kernel shells wholly or partially as a coarse aggregate. This paper therefore presents results of an experimental laboratory investigation carried on PKSC by incorporating varying percentages of granite fines to replace sand in steps of 20% to study its effect on the

Environmental Impact of Aggregates Concrete

Environmental Impact of Aggregates. Aggregates form the major part of concrete and are derived from many types of rock. Granite and limestone are extracted from quarries, crushed and graded. In many parts of the UK, land-based or marine sand and gravel are available: these require some processing, such as washing and grading, before use in
