A.A. Ganie, S. Prakash, light weight concrete (partial replacement of coarse aggregate using polystyrene beads) from Effect of partial replacement of coarse aggregate by ,Light weight concrete (LWC) were made by partially replacing coarse aggregate by polystyrene foam balls. This resulted in a reduction of overall weight of the LWC test beams by approximately 30 % compared to their counterparts of NWC ones.

Control mixing ratio of 1:2:4Partial Replacement of Coarse Aggregate with Palm ,The partial replacement of coarse aggregate with palm kernel shell (which is a waste) in concrete can reduce the overall cost of the concrete and therefore construction also. Cost reduction of concrete with respect to increasing percentage replacement of coarse aggregate is shown in Table 11. TABLE XI. C. OST . R. EDUCTION OF . B. LOCKPartial Replacement of Oyster Shells as Coarse Aggregate ,In our project, those shells are used as partial coarse aggregate replacement in concrete which is an effort towards protecting natural coarse aggregate for future generation. Coarse aggregate is partially replaced with 0%, 5%, 10% & 15% by oyster shells. Grade of concrete adopted is M30. Workability, compressive, split tensile &
In some of the research works carried out, the “Performance of waste coconut shell as partial replacement of natural coarse aggregate in concrete” was used to produce M20 grade concrete by replacing coarse aggregates with coconut shells by 0, 5, 10, 20, 30, 40 and 50% by weight. This research showed that the compressive strength of Thermal Conductivity of Coconut ShellIncorporated ,Coconut shells (CA) were also utilized as the partial replacement of coarse aggregate in concrete to achieve superior performance wherein most of the studies have only experimentally evaluated the effect of CA substitution on the mechanical properties and durability of concrete [35,36,37,38,39,40,41,42].

Coarse aggregate is an important part of concrete as it provides a strong connection between cement paste and finer material, such as pebbles or sand. The combination of these two elements creates a durable and stable building material. Types of Coarse Aggregate. There are four main types of coarse aggregate: 1) Gravel. 2) Crushed stone. Partial replacement of fine aggregate by steel slag and ,Durability tests were conducted for 40% steel slag replaced concrete. The weight and strength loss in cubes after immersion in salt (NaCl), acid (HCl) and sulphate (MgSO4) was very low. So the concrete with partial replacement of fine and coarse aggregate by steel slag and walnut shell shows better resistance in salt, acid and sulphate. •Partial replacement of coarse aggregate by expanded ,As compared to the control concrete, replacement of coarse aggregates by EPT percentages of 0.38, 0.76, 1.3, 1.51 and 1.9 % resulted in density reductions by approximately 17, 33, 44, 57 and 64 % respectively.

For this 10%, 15%, 25%, 30% and 35% replacement of coarse aggregate by expanded polystyrene beads is attempted in this work. 1.1 Expanded Study on Partial Replacement of Coarse Aggregate with ,Abstract. This paper investigates the partial replacement of the coarse material and improves the mechanical properties of concrete. Stainless steel is currently one of the fastest growing sectors in the manufacturing industry due to the increasing use of these metal products in the construction and industrial industries, and considering the highly Crumb Rubber as Partial Replacement of Coarse ,a view to investigating its suitability as partial replacement of coarse aggregates in asphaltic concrete. The waste tyre was obtained from a dump site in Ede and the portion free from steel breeds was cut into smaller pieces and sieved to obtain crumb rubber passing through sieve 12.5mm and retained in 9.5 mm sieve. Asphaltic concrete
