Compressive strength is the standard strength parameter of concrete that can be evaluated under site conditions as well. The most common method is to use cylinder cores drilled off the structure. Momber (1998b) was probably the first to suggest to use the way how a cylinder fails during the compression test as a criterion of the material behaviour during hydrodemolition.
CIP 17 - Flowable Fill Materials WHAT is Flowable Fill? Flowable fill is a self-compacting low strength material with a flowable consistency that is used as an economi-cal fill or backfill material as an alternative to compacted granular fill. Flowable fill is not concrete nor it is used to replace concrete. Terminology used by ACI Committee

The compressive strength of the concrete cylinder is one of the most common performance measures performed by the engineers in the structural design. Here, the compressive strength of concrete cylinders is determined by breaking the cylinders in a compression-testing machine.
Compressive or flexural strength of concrete is easily measured in a number of ways for different types of specimens. Gilson Compression Testing Machines are the stiffest in the industry and meet or exceed ASTM C39 requirements and ACI 368 recommendations for rigidity.

The capacity of concrete is reported in psi – pounds per sq. inch in US units and in MPa – mega pascals in SI units.This is usually called as the characteristic compressive strength of concrete fc/ fck. For normal field applications, the concrete strength can vary from 10Mpa to 60 Mpa.
Key Words: Concrete, Fly Ash, specific Gravity, Compressive Strength, Density and RCPT. 1.0 INTRODUCTION The cost of materials is currently so high that only governments, corporate organizations and wealthy individuals can afford to do meaningful construction. The use of high volume fly ash concrete fits in very well with sustainable development.
AAC is strong enough to use for structural parts of a building, but isn't as strong as conventional concrete. According to the Portland Cement Association, autoclaved aerated concrete has an allowable shear stress of 8 to 22 psi, and a compressive strength of 300 to 900 psi.
The quality of concrete is judged largely on the strength of that concrete. Equipment and methods are continually being modernized, testing methods are improved, and means of analyzing and interpreting ...
