Finally after 1 week and after 4 weeks slump values (consistency of the concrete) and compressive strength were measured without mixing any admixture or superplasticiser.

Properties of recycled concrete aggregate under different curing .

This reduces the consumption of natural resources as well as the disposal of waste concrete in landfills [1]. Thus the idea of using recycled concrete aggregate in new concrete production appears to be an effective utilization of concrete waste. However, the strength of new concrete produced using recycled concrete.

Effects of the Parent Concrete Properties and Crushing Procedure .

The most important parameters associated with recycled concrete aggregate (RCA) production that may affect quality and yield include such properties of the parent concrete as the composition, strength and aggregate grading, type of crushers used, number of crushing stages, the size of the RCA particles, and the size.

Preparation and properties of high-strength recycled concrete in .

While China began to study concrete waste recycling fairly late in the day, the country has recently engaged in more intense research on the subject, as attested to by the literature (9, 10). Nonetheless, many issues are still in need of more indepth study. The properties of high-strength recycled concrete have been the object.

New type of crushed sand to replace natural sand in concrete .

It is also worth mentioning here that crushed fine aggregates normally outperform natural sand when the most essential hardened concrete properties, such as compressive and tensile strength, are compared. At the same time, the problems of achieving economical mixes with suitable workability (fresh state properties of.

Green Concrete from Sustainable Recycled Coarse Aggregates .

Jan 15, 2015 . Improvements in all the engineering properties of hardened concrete were observed using washed recycled coarse aggregates. The compressive strength of 28-day hardened concrete containing washed recycled aggregate was slightly lower (7%) than concrete prepared with natural aggregates.

Recycling of waste glass as a partial replacement for fine aggregate .

The strength properties and ASR expansion were analyzed in terms of waste glass content. An overall quantity of 80 kg of crushed waste glass was used as a partial replacement for sand at 10%, 15%, and 20% with 900 kg of concrete mixes. The results proved 80% pozzolanic strength activity given by waste glass after 28.

A Study On The Strength Of Concrete Using Crushed . - IJRASET

Abstract -- The purpose of this study was to investigate the possibility of using crushed stone dust as fine aggregate partially or fully with different grades of concrete composites. The suitability of crushed stone dust waste as a fine aggregate for concrete has been assessed by comparing its basic properties with that of.
