  • Compressive Strength of Concrete -Cube Test, Procedure

    Procedure for Concrete Cube Test. Remove the specimen from the water after specified curing time and wipe out excess water from the surface. Take the dimension of the specimen to the nearest 0.2m; Clean the bearing surface of the testing machine; Place the specimen in the machine in such a manner that the load shall be applied to the opposite sides of the cube cast. Align the specimen

  • Compressive Strength of Concrete Cube Test Procedure

    Procedure: Compressive Strength Test of Concrete Cubes For cube test two types of specimens either cubes of 15cm X 15cm X 15cm or 10cm X 10cm x 10cm depending upon the size of aggregate are used. For most of the works cubical moulds of size 15cm x 15cm x 15cm are commonly used.

  • Aggregate Crushing Value Test Procedure And Result

    Aggregate crushing value test provides the resistance of an aggregate sample to crushing under gradually applied compressive load. Generally, the test is conducted on aggregate passing 12.5 mm and retained on 10 mm sieve. The aggregate sample is filled in a cylindrical mold and a load of 40 ton is applied through a plunger in a compression testing machine.

  • 9.2 Crushing Strength of Concrete 9.2.1 Introduction

    Chapter 9 Standard Test Procedures Tests On Concrete MAY 2001 Page 9.5 9.2 Crushing Strength of Concrete 9.2.1 Introduction Crushing tests are universally used for determining the strength of concrete and the standard test measures the crushing strength at an age of 28 days after mixing. Because of the time delay in obtaining the test results for concrete crushing strength, it is often very

  • Compressive Strength Test of Concrete Detailed Guide

    Otherwise, the compressive strength of concrete is defined as the maximum crushing stress endured by the concrete. Purpose of this Test. Assume a slab at our site is designed to cast M25 grade of concrete, but we could not define its strength in the semi-solid state. For that matter, A certain quantity of concrete shall be cast as a cube while

  • Compressive Strength of Concrete Cube Test, Procedure

    Procedure for Compressive strength of concrete or Cube test :-Place the prepared concrete mix in the steel cube mould for casting. Once it sets, After 24 hours remove the concrete cube from the mould. Keep the test specimens submerged underwater for stipulated time.

  • Procedure for Concrete Compression Test Concrete

    Test process for Compression Test. The compression test shows the best possible strength concrete can achieve in perfect conditions. The compression test measures concrete strength in the hardened state. Field concrete samples are prepared, cured and tested according to ASTM standard procedures. Specimens are prepared from concrete taken from

  • A Simple Guide to Concrete Cube Testing

    Concrete is one of the most widely used building materials in the world, yet people still find it difficult to take samples correctly and manage the testing & certification process. Failure to do this can result in the need to spend even more money undertaking complicated calculations to prove compliance with British Standards or even drilling and crushing cores to prove design and reliability!

  • Tests on Concrete Concrete Slump Test, Compression

    Procedure of slump test for concrete: Clean the cone. Dampen with water and place on the slump plate. The slump plate should be clean, firm, level and non-absorbent. Collect a sample of concrete to perform the slum test. Stand firmly on the footpieces and fill 1/3 the volume of the cone with the sample. Compact the concrete by 'rodding' 25 times. Rodding means to push a steel rod in and out of

  • Aggregate Crushing Value Test Cement Concrete

    Procedure The aggregate sample: The material for the standard test consists of aggregates sized 10.0 mm to 12.5 mm .The aggregates must be in surface dry condition before testing. The aggregates may be dried by heating at 100 oC 110 o C for not mor than 4 hours and cooled to room temperature before testing, if necessary.
