Procedure of Concrete Compression Test A Civil Engineer

Updated March 17th, 2019Concrete compression test is done to know the concrete compressive strength. It is one of two well known concrete test. Another one is slump test. For this purpose, either concrete cube or cylinder specimens are tested in the laboratory.3 concrete specimens are generally made and cured for 28 days at site and […]

Recycling of Demolished Concrete and Ewaste

The specimens used for testing include cubes, cylinders and beams. In this project comparison between fresh concrete materials, waste concrete material, and E-waste concrete material for compressive strength, tensile strength, flexural strength and bond strength. The main aim of this study recommends the recycling of waste concrete as an aggregate

Ways to Recycle and Reuse Concrete

Base for new asphalt paving: Through a process called rubblization, old concrete pavement can be broken in place and used as a base layer for asphalt pavement laid over it. Bed foundation material for trenches containing underground utility lines: Utility trenches are oven covered with gravel to assist drainage, and crushed concrete makes a good, inexpensive substitute for gravel.

HOW TO MAKE TEST CUBES FROM FRESH CONCRETE?

Sep 23, 2016 · The cubes shall be tested in the saturated and surface dry condition. For the true representation of actual strength of concrete in the structure, extra cubes shall be cast, stored and curded as per the identical conditions of that structure, and tested at required age.

Lab Experiments: MAKING TEST CUBES FROM FRESH CONCRETE

MAKING TEST CUBES FROM FRESH CONCRETE: Compaction: Filling the Cube Moulds and Compacting the Concrete. After the sample has been remixed, immediately fill the cube moulds and compact the concrete, either by hand or by vibration. Any air trapped in the concrete will reduce the strength of the cube. Hence, the cubes must be fully compacted.

Quality Control Of Construction Testing Of Concrete Cubes

TESTING OF CONCRETE CUBES: The dimensions of the specimens to the nearest 0.2 mm and their weight shall be noted before testing. The bearing surfaces of the testing machine shall be wiped clean and any loose sand or other materials removed from the surface of the specimen which are to be in contact with the compression platens.
