Feb 06 2017 Compressive strength in concrete test 1. COMPRESSIVE STRENGTH CONCRETE IS STRONG IN COMPRESSION AND WEAK IN TENSION PREPARED BY S.Selvaprakash 2. COMPRESSIVE STRENGTH Compressive strength is the capacity of a material or structure to withstand axially directed pushing forces.
Jul 18 2019 ASTM C 192 was used as the guide for making and curing concrete test specimens in the laboratory . The specimens were demolded after 24 hours and submerged underwater until a day before testing. UPV and the axial compression machine ACM in Figure 4 were used to determine the compressive strength of concrete at days 7 and 28.

the compressive strength of concrete. 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.

In this investigation an approach using a feedforward neural network FNN machine learning algorithm was proposed to predict the compressive strength of later-age concrete.

Concrete compressive strengths of 35 and 60 MPa 038 and 055 mm fibre diameter and 30 mm fibre length were considered. The volume of fibre in the concrete was varied up to 1.5. Test results indicated that the addition of fibres to concrete enhances itstoughness and strain at peak stress but can slightly reduce the Youngs modulus.
NOTE Due to doubtful concrete the work was stop. Concrete was tested by rebound hammer and drilled cores. From test results the foundation concrete found to be of M25 grade. The work was started only when new cube moulds properly calibrated compression testing machine was purchased and laboratory staff was trained in all the site testing work.
The sample was then tested in compressive strength testing machine as shown above and below. Recommended limit for compressive strength of the concrete is 2-7 Nmm 2 amp the calculated result came to be 3 Nmm 2. Flow test This test gives an indication to the quality of concrete with respect to consistency cohesiveness amp the proneness to .
Compressive strength of cement at 7 days amp 28 days. Compressive strength of cement is determined by cube test on cement mortar cubes compacted by means of a standard vibration hydraulic machine. Standard vibration for making cube is 12000 - 400 vibration per minute and it will vibrate for 2 minute.
May 07 2021 By the compressive test we can make sure proper concreting as the compressive strength plays a major role in concrete. The concrete mix is designed as per the requirement and serviceability of the structure for general construction 15 MPa 2200psi to 30 MPa 4400psi and it could be higher as per structure need.
Concrete cube testing or cylinder testing is done to check the development of the strength of the concrete. In other words we test the concrete to check whether it has reached or developed beyond the characteristic strength of concrete assume in the design. Based on the test results conformity can be checked as per the relevant standards.
Concrete compression machines MIP-25 and MIP-50 are designed for quick quality control of concrete and other building materials - to test bored cylinders up to dia. 70x100 mm - for determination of compression strength of concrete and mortar cubes of 70 mm and 100 mm side Used as the mobile or laboratory testing machines
