The study examined the effect of the recycled HCB on fresh and hardened C-25 concrete properties and the possible replacement percentage of river sand by those recycled fine aggregates. The research also examined the comparative properties of the two recycled fine aggregates.

Sieve Analysis of Aggregates

Sieve analysis helps to determine the particle size distribution of the coarse and fine aggregates.This is done by sieving the aggregates as per IS: 2386 (Part I) – 1963. In this we use different sieves as standardized by the IS code and then pass aggregates through them and thus collect different sized particles left over different sieves.

Concrete recycling

In general, the reuse and recycle of construction waste is concentrated in the preparation of recycled aggregate for concrete. By adding a portion of recycled aggregate instead of natural aggregate coarse into the mixture, producing the recycled concrete, which can conserve energy and materials for concrete production.

Distribution of fresh carbon in different particle-size

In order to study the effects of application of fresh carbon on distribution in soil aggregate fractions of red soil and lime concretion black soil, the stable carbon isotope (δ 13 C) technique was used, and explore the dynamic variation and distribution of soil organic carbon(SOC) in soil aggregates during 13 C-labelled rice straw decomposition by an indoor incubation experiment.

Recycling of Waste Polymeric Materials as a Partial

Abstract- The potential of recycled waste polymeric materials as a substitute for aggregates in concrete has been investigated in the study. Three types of waste polymer, namely expanded polystyrene (EPS) based packaging waste, high density polyethylene (HDPE) and vehicle tire were used in the experiment. Assessment was carried out
