Standard Test Methods for Sampling and Testing Concrete

1.1 These test methods provide various testing procedures commonly used for evaluating characteristics of concrete masonry units and related concrete units. Methods are provided for sampling, measurement of dimensions, compressive strength, absorption, unit weight (density), moisture content, flexural load, and ballast weight.

Concrete Testing Procedures Tests for Slump & More The

The measurement of air content in fresh concrete of normal density is typically performed using the pressure method (ASTM C 231). Another useful test is ASTM C 173. However, the pressure method is frequently preferred because it is relatively fast. You should begin the test within 15 minutes after obtaining the composite sample.

Testing of Hardened Concrete Compression, flexural, non

9. Surfaces Hardness Methods: The fact that concrete hardens with increase in age, the measure of hardness of surface may indicate the strength of concrete. Various methods and equipments are devised to measure hardness of concrete surface. William testing pistol, Frank spring hammer, and Einbeck pendulum hammer are thus some of the devices for

Non Destructive Testing Methods Bridge Inspection And

Various type of non destructive testing methods have been developed and are under development for examining different properties of concrete in addition to the necessary visual inspection. Tests are aimed at assessment of strength and other properties and to locate and obtain corresponding results showing permeable areas, cracks or laminations

Non-Destructive Methods of Testing Concrete Concrete

Method # 2. Penetration Resistance Test: During 1964-66, a technique or test was developed for concrete testing in the laboratory as well as in-situ. Commercially this test is called as Windsor probe test. The strength of the concrete is estimated from the depth of penetration of a metal rod driven by a standard charge of powder.

Comparison of Pulse-Echo-Methods for Testing Concrete

When some of the established methods used in other areas of materials testing are applied to concrete testing, certain difficulties are encountered as concrete is an inhomogeneous, porous building material.

Maturity Method A Guide to Concrete Strength Giatec

Maturity is a non-destructive approach to testing concrete that allows you to estimate the early-age and compressive strength of in-place concrete in real-time. Adopting the maturity approach in your jobsite eliminates the need for concrete cylinder break tests, allowing you to greatly optimize your schedule.

Ultrasonic Testing of Concrete FPrimeC Solutions Inc.

Apr 13, 2017 Ultrasonic Pulse Velocity (UPV) is an effective non-destructive testing (NDT) method for quality control of concrete materials, and detecting damages in structural components. The UPV methods have traditionally been used for the quality control of materials, mostly homogeneous materials such as metals and welded connections.

How to Conduct a Moisture Test for Concrete Floors

Three Methods for Testing Concrete Moisture Levels It is vitally important to test your concrete slab's moisture before installing flooring over it. A definitive test that measures the amount of moisture released from the concrete requires a calcium chloride kit or a relative humidity meter .

ULTRASONIC TESTING OF CONCRETE Civil Engineering

It is better if similar concrete at the same time be tested with one more non-destructive test method, such as concrete test hammer etc. for conclusive results. REFERENCES 1. IS: 13311 (Part 1): 1992, Non-destructive testing of concrete Methods of test, part 1

Cement Standards and Concrete Standards

ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.
