Abstract: A light weight concrete block using granulated corncob as an aggregate is investigated in this research work. Considering corn cob after removing the corn is said to be agricultural waste. Finding practical uses of this waste for manufacturing concrete block may preserve the environment and also allow green technologies. These concrete blocks are studied in terms of compressive strength, water absorption; density and unit weight were experimentally studied. The results obtained are submitted which shows that corn cob blocks have sufficient material properties for non-structural application in building for construction of partition walls. This is the alternative for blocks in expanded clay, expanded polystyrene, particles of cork, coconut coir etc. In this research a clay brick is compared as a reference block or control block. Nine specimen blocks were prepared in a size of 400mm x 200mm x 100mm and cured for 7 days, 14 days and 28 days and subjected to compressive strength test, water absorption test and density. The results are compared with conventional clay bricks. Corn cob blocks offered a good strength, low density and less water absorption.

The aim of this research is to study about physical, mechanical, and thermal insulation properties of light weight concrete block products mixed with ethylene vinyl acetate plastic scrap (EVA) from shoe factories. The ratio of cement: aggregates (quarry dust + EVA): water is 1:4.5:1.66 by weight. EVA to cement ratios (E/C) are fixed at 0.00, 0.33, 0.42, 0.50 and 0.58. The concrete block samples are cast for testing the necessary properties followed the TIS standard 58-2533. From the experiment, EVA plastic with the appropriate size and quantity are well adhesive with cement as well as quarry dust mixture. The least density of light weight concrete block mixed with waste of ethylene vinyl acetate plastic products is 640 kg/cu.m. The appropriate mixtures of light weight concrete block mixed with EVA plastic scrap can reach the required values from the standard of TIS 58-2533 and can be used as a thermal insulation wall.

Materials Used

The development of structural materials used in the building process is certainly subject to the local and temporal potentials and to how the extent to which the human thought made in the scientific and industrial field. Where the constructional methods that depend on pottery, bricks were and still essentially adopted. The advanced human thought attempted making more efforts to find constructional materials of certain specifications. Porous concrete Light Weight Concrete (LWC) is considered a good alternative constructional material in addition to its light weight and good thermal isolation. It is currently used in Iraq as concrete block to form breakers only. This research includes essential information about LWC and developing it through the adding paraffin wax to generate a material of high moisture isolation, low absorption rate and high bearing for compressive forces especially after overflowing it with wax.
