LITERATURE REVIEW • The applications of recycled aggregate in the construction area are very wide. There are many testing based on the recycled aggregate have been carried out all around the world. • Hanson and Torben (1986) stated that since 1945, the research on recycled aggregate had been carried out in many countries.
The present study compared angularity, texture, sphericity and flat & elongation (F&E) ratio of three different sizes (P19-R12.5, P12.5-R9.5 and P9.5-R4.75) of coarse aggregate produced from two ...

E- waste is used as one such alternative for coarse aggregate. Owing to scarcity of coarse aggregate for the preparation of concrete, partial replacement of E-waste with coarse was attempted. The work was conducted on M20 grade mix. The percentage of replacing coarse aggregate with E-waste in the range of 0%, 5%, 10%, 15%, and 20%.
Based on the current production line of artificial aggregate, the waste concrete derived from the same source was crushed by different crushing machine, jaw crusher and impact crusher.

This paper reports the result of a research undertaken to investigate the effect of three different types of coarse aggregate on the compressive strength of normal concrete. Several models were proposed and statistically validated. ... Effect of aggregate type on Compressive strength of concrete
aggregate in concrete in place of natural fine aggregate. For that an experimental programme was carried out to study the suitability and potential use of stone dust as partial replacement of fine aggregate in concrete. To accomplish this specimen were cast for different replacement level at …
Oct 29, 2019· The crushing tests were carried out with the same dimension of outlet slot e r = 24 mm, close to the pitch size for plates with triangular profile. Tests were performed on the "Mucharz" sandstone. Samples from a series of blocks of different size and geometric shape were prepared.
May 14, 2015· Aggregate crushing value (ACV) provides an indication of the aggregate strength. Aggregate with lower ACV is recommended to ensure that the aggregate will be able to resist applied loads. The test was conducted on coarse aggregate of different grades. The ACV is calculated as the ratio between the weight passing sieve 2.36 and the original weight.

The water absorption of recycled concrete aggregate is higher than natural aggregate which results in an increase in water cement ratio to get required workability of concrete. The resistance of recycled aggregate to mechanical actions i.e., impact and crushing is lower than natural aggregate, but the values are in acceptable limits.
coarse aggregate with coconut shell aggregate is determined from the study. Coarse aggregate made from coconut shells were used in proportions of 5%, 10%, 15%, 20%, 25%, 30% and 35% to replace coarse aggregate in conventional concrete. A constant water to …
Several studies,,, on high-strength concrete (HSC) have been developed with the objective of studying the influence of coarse aggregate from different mineralogical sources. However, few studies have been conducted on the influence of different crushed sands and the codes only include brief requirements for fine aggregates .

partial or full replacement to river sand is the need of the hour as a long term solution in Indian concrete industry until other suitable alternative fine aggregate are developed. In the present study, a comparison of the Compressive strengths of River Sand and M-sand is done with the hundred percent replacement of river sand by M sand. Index ...
A cost comparison of concrete pro-duced using partial or full replacement of the Natural Sand with Manufactured Sand was made. The results were pre-sented in graphical form and interpretation and discussion were made on the research findings. Based on the findings conclusions are drawn and recommendations are for-warded. 2.1 Fine Aggregate
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.
Regarding the assessment of the effect of different rock type on the aggregate shape properties, the t-tests are conducted based on each rock type. For this purpose, t-tests are conducted by considering the same rock type and different crusher, for examples between JL and IL in the first line of Table 4.
This paper describes a study of the effects of several factors on the strength of lightweight aggregate concrete composites: aggregate strength, w/c ratio and the porosities of the interfacial zone and within the hardened cement paste. Concrete samples with three different water cement ratios (i.e. 0.4, 0.44, 0.48) were compared.

Sep 12, 2015· Tests on Aggregate Aggregate plays an important role in pavement construction. Aggregates influence, to a great extent, the load transfer capability of pavements. Hence it is essential that they should be thoroughly tested before using for construction. Not only that aggregates should be strong and durable, they should also possess proper shape and size to […]
In comparison to natural alluvial gravel or manufactured crusher-run aggregate, the milling process produces proportionally fewer particles ﬁner than the #4 sieve. Changes observed in the upper region of the gradation curves were attributed to the particle size characteristics of the RAP millings, which in Project Summary Report 8117-24
this data is necessary on fine aggregate for other purposes, such as mix design and water/cementitious ratios. All aggregates are porous, but some are more porous than others. How porous an aggregate is determines how much liquid can be absorbed when soaked in water. The test method AASHTO T 85 defines absorption as
