STP169D Significance of Tests and Properties of Concrete

In this test, a beam of concrete is cast in standard dimensions depending upon the nominal size of the aggregate. Then, the beam is properly cured and tested after 28 days. In the second indirect method , called the split-cylinder method, the cylinder of specified dimensions is made to fail under tension by applying compressive load across the

For the ASTM C143 and AASHTO T 119 slump test, A Slump Cone is placed on a solid, level base and filled with fresh concrete in three equal layers rodded in a specified manner to consolidate. The concrete is struck even with the top of the cone, and the cone is carefully lifted away. The sample then settles, or slumps and the final height is subtracted from the original height of the cone and

Compressive strength testing of concrete:-The test is carried out using 150mm concrete cubes on a Universal testing machine or compressive testing machine. Apparatus. As per IS: 516-1959 Compressive testing machine (2000Kn),15cm×15cm×15cm steel cube molds or Cylinder having Dia 15cm and length 30cm are used. The test includes following steps:-

4. Flow Test for Workability of Concrete-Flow test gives the satisfactory performance for concretes of the consistencies for which the slump test can be used. The test consists of molding a fresh concrete cone on the top of the platform of the flow table, and in giving 15 jolts of 12.5 mm magnitudes.

Compressive strength testing is included in this study in order to assure the quality and control of the mixtures. In the instance that additional specimens are required, a compressive strength test of the newly produced concrete can help confirm uniformity between previous and new batches of concrete.

Shrinkage of Concrete. Presently we shall discuss the volume change on account of inherent properties of concrete "shrinkage". One of the most objectionable defects in concrete is the presence of cracks, particularly in floors and pavements. One of the important factors that contribute to the cracks in floors and pavements is that due to

2.4.3 Testing of SCC 2.4.3.1 Introduction The properties that differentiate SCC from conventional concrete are those of the fresh concrete. The required workability for casting concrete depends on the type of construction, selected placement and consolidation methods, complexity of the formwork, and structural design details that affect the

Concrete is an essential element for building a structure, as it enhances and improves the sustainable performance. We cannot overlook the use of concrete in society as it plays a vital role in the
