Adoption of Recycled HDPE Plastic Granules and waste Crushed Glass as a Partial Substitute of fine Sand in Concrete Effect of incorporating the PVC granules as lightweight aggregate in concrete, the densities and workability of lightweight concrete were decreased. The compressive strength and split tensile strength were decreased. The ductility of PVC (Poly Vinyl Chloride) concrete was enhanced. And he said that PVC granules are utilized as aggregate to restore the sand for making lightweight concrete the optimum usage of PVC granules are up to 15%. Malek Batayneh et al [8] Studied on three different mixes as a fine sand replacement with the waste materials waste glass, waste plastic and demolished concrete. The results are shown by replacing the waste broken glass as fine sand in a concrete increase in a slump value and compressive strength and split tensile by rising the proportion of crushed waste glass. The results are shown by replacing the waste plastic and demolished concrete aggregate in concrete decreases in a slump and compressive strength and split tensile by rising the percentage of discarded plastic and recycled aggregate. Ismail Zainab Z. and Al-Hashmi A [9] stated that the performance of crushed waste glass in the concrete mix as fine aggregate shown the increase in compressive strength and flexural strength by increasing the proportion of crushed glass in concrete. III. MATERIAL SPECIFICATIONS A. Cement 5 C. Fineness modulus of Fine aggregates HDPE plastic granules 3.15 7.36 The materials used in mix design cement, fine aggregate and coarse aggregate should satisfy the code IS 10262-2009 [35]. And fine aggregates are river sand, HDPE plastic granules and crushed glass. The waste HDPE plastic is gathered and it is recycled into the granules. In this paper, the HDPE plastic granules are collected from Hyderabad, Jeedimetla [17], plastic factory.

The physical properties of fine aggregate are tabulated below. (Table 3.2) Coarse aggregate used in this was angular of size 12.5mm confirming to IS 383-1970 [10]. The physical properties of Coarse aggregate are tabulated below.

Concrete mix design is the methodology for finding the correct amounts of these materials to accomplish the ideal quality. Exact concrete mix makes concrete construction practical and economical. The mix proportions are tabulated below. Published By: Blue Eyes Intelligence Engineering & Sciences Publication IV.
