One of the solutions is to use crushed sand to replace natural sand as aggregate in concrete, especially the study of using crushed sand to make high-strength self-compacting concrete. Crushed sand is an aggregate of angular shape and surface roughness that hinders the self-compacting of the concrete mixtures.

In this study, the durability of pervious concrete, with or without the crushed seashells, are studied by: freeze-thaw resistance test with and without deicing salt, clogging test and leaching test. The shell pervious concrete was created by replacing 60% mass of the natural aggregates in control pervious concrete by crushed seashells.

The grade of concrete used for the research work was C-30/37 grade concrete with Portland cement CEM-I, 52.5N class cement as per BSEN-197, Part-1 with w/c ratio 0.4 and coarse aggregate used for the experiment is crushed basalt rock. The experiment was conducted by taking two 44 mm diameter core from each cube specimen after 28-days of

materials to replace sand. This study aimed to investigate the suitability of using crushed brick in concrete. Crushed brick originated from demolished masonry was crushed in the laboratory and added partial sand replacement. Three replacement levels, 15%,20% and 25%, were compared with the control.

Based on the results high volume fly ash-based green concrete was made using siliceous fly ash. Concrete mix M20 is designed with water-cement ratio 0.42 by adding 50% of fly ash (Siliceous/Class-F) as a partial replacement of cement, without using any chemical admixture. Six concrete cubes of size 150 mm x 150 mm x 150 mm are cast with water ...

Where a portion of coarse aggregate (gravel) and coarse sand up to the diameter of 2.38 mm included in the composition of the reference concrete mixture aggregate (consisting of 30% recycled gravel and 70% natural limestone gravel) has been replaced by crushed red brick aggregate by 20%, 40%, 60%, .

Concrete samples were prepared and cured in the laboratory, and are tested, to evaluate the concrete fresh and harden properties like compressive strength, Split tensile strength and flexural strength requirements. A. Partial replacement of Sand with Copper slag results 1) Slump Cone Test

International Journal of Engineering Trends and Applications (IJETA) – Volume 5 Issue 3, May-Jun 2018 ISSN: 2393-9516 Page 73 2.1.2 FINE AGGREGATES: Sand is a natural granular material which is mainly composed of finely divided rocky material and mineral

crushed limestone sand concrete compared with those of crushed granite sand concrete and river sand concrete. The test results showed that the fracture energy of con- crete was little influenced by the type of fine aggregate. In addition, the fracture energy of crushed sand concrete was slightly higher than that of river sand concrete. Also ...

compared with respect to crushed sand and stone dust of five types of locally available materials. Simulation of test results were found suitable in terms of MORTH requirements in use of WMM construction and found a saving of cost of 6% to 13% by using such materials.

crushed rock sand. In each case, the cube compressive strength test, and beam flexure tests were conducted. The results of the study show that, the strength properties of concrete using crushed rock sand are nearly similar to the conventional concrete. The study has shown that crushed stone sand can be used as

18-08-2020· Recycled concrete aggregates also called Crushed concrete aggregates are fragments and pieces of concrete buildings that are demolished or rebuild. This crushed concrete is cleaned from dirt and broken into smaller pieces to manufacture aggregate which is termed as Recycled Concrete Aggregate or Crushed concrete aggregate.

Aug 23, 2019· Hence, one can replace the river sand up to 25%-50% in the concrete mixes. This type of replacement has a lot of advantages to the environment as well as human kind. Therefore, replacement of river sand with construction and demolition waste is recommended. Also Read: Recycled Concrete Aggregates: Its Properties & Uses. Get More
