Effect of Crushed Tiles Aggregate and Oil Palm Additive on ,Utilization of crushed clay brick in concrete industry

Prasad et al [10] in their study on crushed waste tiles and granite powder as a replacement to the coarse aggregates and fine aggregate discovered that there was increment of % and % for compressive strength after 7 and 28 days of curing when compare to the conventional concrete strengthThe first use of crushed brick with Portland cement was recorded in Germany () for the manufacture of concrete products, but the first significant use of crushed brick as aggregates in new concrete has been recorded for reconstruction after World War II.

New cement mixtures could turn buildings into batteries ,The Effect of Aggregate Properties on Concrete

Buildings and bridges could be turned into cheap batteries with the discovery of new cement mixtures, says researchers at Lancaster University, in the UK aggregateresearch

The first one is a mixture of 1:2:4 without crushed bricks and is used as a reference mixture The second one is made of different weight of crushed bricks (as a percentage from the weight of the coarse aggregate) A total of 30 numbers of concrete specimens are casted with and without crushed bricks and tested under compression and split tension as per relevant to British standard .The utilization of crushed tile as a coarse aggregate in concrete would have a positive effect on the economy In concrete production, Portland cement, river sand, 4-32 mm in size crushed stone.

AggregatesQUALITY OF AGGREGATE FOR ASPHALT CONCRETE

Aggregates strongly influence concrete's freshly mixed and hardened properties, mixture proportions, and economy Consequently, selection of aggregates is an important process Although some variation in aggregate properties is expected, characteristics that are considered include:-12-24 Aggregates are subjected to additional crushing and abrasive wear during manufacture, placing, and compaction of asphalt concrete mixtur Aggregates are also subjected to abrasion under traffic loads They must exhibit an ability to resist crushing, degradation, and disintegration The Los Angeles Abrasion test measures wear abrasion resistance of aggregat.

COMPARATIVE STUDY OF USING STEEL SLAG AGGREGATE AND ,Different Types & Sizes of Aggregate for Concrete

concrete mixtures using steel slag aggregate is 150 higher than mixtures with Crushed limestone aggregate From the result it can be seen that using steel slag aggregate is useful for resist rutting andA mixture of all sorts of aggregates, it is appropriate as a base for concrete in projects that do not require precise aggregate-to-cement ratios [5] RECYCLE CONCRETE Recycled concrete is created by breaking, removing, and crushing existing concrete to a preferred size.
