Recycling of Brick Aggregate Concrete as Coarse Aggregate

Jul 07, 2015 Based on this investigation, it is revealed that recycled brick aggregate can be used as coarse aggregate for making concrete of strength 20.7 to 31.0 MPa. For the same mix design, the recycled aggregate concrete produces almost similar strength compared with the virgin first class brick aggregate concrete commonly used in Bangladesh.

the seashell as a coarse aggregate in concrete along with partial replacement of cement by flyash of 25%. Further it was planned to extend the studies into workability characteristics while using seashell as partial replacement. This can be effectively used for the improved concrete construction with local materials. III.

Concrete aggregate is a material which is mixed with cement to create concrete which is hard, strong, and long-lasting. There are a number of different types of concrete aggregate, with contractors selecting their aggregate on the basis of the type of job being performed. If you live in an area with concrete structures, you may be able to see

Concrete made from coconut shell waste as coarse aggregate will be studied for compressive strength, tensile strength and flexural strength. the percentage replacement will be 0%, 10%, 20% and 30% with natural coarse aggregates and replacement of 10% various size of coconut shell in concrete. the

The concrete mixes using brick or glass as 10%replacement of cement exhibited enhancement in compressive strength about (6, 4.7 and 2.0)% and (7.2, 5.6 and 2)% at age 7, 28 and 90 days

Mar 05, 2019 In some situations, dry or semi-dry mixture of concrete i.e. cement, fine and coarse aggregate are filled in cement bags and such bagged concrete is deposited on the bed below the water. This method does not give satisfactory concrete because the concrete mass will be full of voids interspersed with the putrescible gunny bags.

Key words: coarse aggregate, granite waste. INTRODUCTION: Concrete is a composite material composed of aggregate bonded together with the fluid cement which hardens over time. Most use of the term concrete refers to Portland cement concrete or to concrete made with other hydraulic cements. In Portland cement concrete

Sep 12, 2012 instead of common natural rock aggregates. The replacement of aggregates was partially or completely in the concrete according to the mix designs required in terms of weight and strength. 1.1 Shredded tires Old abandoned tires from cars, trucks, farm and construction equipment

Coconut Shell as Partial Replacement for Coarse

replace the aggregate in concrete. Lightweight concrete is typically made by incorporating natural or synthetic lightweight aggregates or by entraining air into a concrete mixture. Coconut shell exhibits more resistance against crushing, impact and abrasion, compared to crushed granite aggregate.

4. Slump loss of concrete goes on increasing with increase of quantity of fly ash. 5. The 10% and 20% replacement of cement with fly ash shows good compressive strength for 28 days. 6. The 30% replacement of cement with fly ash ultimate compressive strength of concrete decreases. 0 10 20 30 40 50 m 0% 10% 20% 30% % of Fly ash 0 5 10 15 20 25 30

The aggregate which passes through 4.75 mm IS sieve and retain on 75 microns IS sieve are known as fine aggregates. Fine aggregate is basically sands won from the land or the marine environment. Fine aggregates generally consist of natural sand or crushed stone with most particles passing through a 9.5mm sieve.

Partial Replacement of Coarse Aggregate with Broken Ceramic Tiles in Concrete Production Yiosese A. O., Ayoola A. R., Ugonna M. C., Adewale A. K. Abstract— The study reports on experimental investigation on the suitability of the use of broken tiles as partial replacement for crushed granite in concrete production.

[Show full abstract] replace the aggregate in concrete. In this study, three different concrete mixes namely M20, M35 & M50 grade with different combination of natural material CS content in the

Abstract— Concrete is considered the world’s most used construction material. Typical concrete mixtures are comprised of water, sand, cement and an aggregate of rock. This project focuses on the coarse aggregate in concrete. The other material will be used to replace the coarse aggregate of rock in typical concrete.

replacement for conventional aggregate. f Concrete is a construction material composed of cement, fine aggregate (sand) & coarse aggregate mixed with water which hardens. with time. Concrete is one of the most widely & continuously using as a construction material in the world wide in which cement and aggregate.

It was advised that aggregate made from quartzite to be used for the concrete work. The study was made for the properties of concrete with coconut shells as the replacement of aggregate [2]. The concrete with normal aggregate as well as coconut shell (CS) concrete with 10-20% coarse aggregate replacement



concrete strength compare with control concrete. The graphical representation shows the flexural strength of copper slag. Fig.7. Comparison of Flexural Strength of Beam IV. CONCLUSION The concrete was prepared for the M 25 grade concrete with partial replacement of fine aggregate by copper slag with various percentages of 0%, 10%, 15% and 20%.

specimens with partial replacement of E-waste on a percentage of 10%, 20%, and 30% to coarse aggregate with water cement ratio of 0.45. For conventional specimens are also prepared for M20 Concrete without using E- waste aggregates. The effect of physical, and mechanical properties of the concrete were studied.

available copper slag and utilization of copper slag in concrete by replacing it partially by fine aggregate keeping the other parameters constant. Compressive strength of concrete cubes on M20 grade of concrete with constant 0.50 w/c ratio. Copper slag replacement of 0%, 10%, 20%, 30%, 40%, and 50% are used.

Sieve sizes commonly used for concrete aggregates are detailed in Table 1, and various physical properties of normalweight aggregates, with typical range values, are shown in Table 2. Coarse and fine aggregates are generally sieved separately. That portion of an aggregate passing the 4.75 mm (No. 4)

In this study, M40 cement concrete is considered in which the recycled plastic waste is used as the replacement of fine aggregate in the concrete. Concrete cubes were cast taking 10%, 20%, 30 %, 40% & 50% of plastic as partial replacement of fine aggregate and tested for 7 & 28 days of compressive strength of concrete.

Replacement of fine aggregate with plastic in concrete

The use of blast furnace slag aggregates in concrete by replacing natural aggregates is a most promising concept because its impact strength is more than the natural aggregate. Steel slag aggregates are already being used as aggregates in asphalt paving road mixes due to their mechanical strength, stiffness, porosity, wear resistance
