Brick Buying Guide

2019/10/14There are 500 bricks in a cube (about a pallet's worth). Always use the correct mortar mix for the job, and use the appropriate mortar joint style to make your project weather-tight. Due to its natural origins, matching brick color isn't easy, so buy enough to complete your project (and include some extra for breakage or later repairs). Get price

Core testing for strength

Core testing for strength Cores are cut using a drill with a hollow barrel tipped with industrial diamonds. The whole rig has to be firmly fixed in position by weights, anchor bolts, vacuum pads or bracing against other parts of the structure. The preferred core diameter Get price

How to Evaluate Concrete Tests per ACI 318

The concrete can be accepted if BOTH of the following are met: 1. The average of the three cores is equal to or greater than 85% of f'c. 2. No single core is less than 75% of f'c. If the cores don't meet the required levels the following are all options to consider: Get price

EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON CONCRETE

How to Calculate the Load Bearing of Concrete

Knowing the load-bearing capacity of your concrete is essential to make sure that what you plan to have supported by the wall or slab will not be too heavy and cause it to crack and break. While cracks in a slab may not seem like a big deal, the smallest crack represents a large amount of downward pressure that may be crushing pipework beneath the slab. Get price

Everything You Need to Know About Concrete Strength

Tests on Concrete

This test is performed to check the consistency of freshly made concrete.The slump test is done to make sure a concrete mix is workable. The measured slump must be within a set range, or tolerance, from the target slump. Workability of concrete is mainly affected by consistency i.e. wetter mixes will be more workable than drier mixes, but concrete of the same consistency may vary in workability. Get price

Alternative Concrete Demolition Techniques

Breaking concrete from the outside requires overcoming its compressive strength. If, however, it can be broken from within, it's only necessary to overcome the tensile strength which is about 15% of the compressive strength. Dynamite is an option for imploding a Get price

Cube Test to Check the Compressive Strength of Concrete

Immediately after the concrete mixing, concrete is placed in the concrete cube mould in the three layers of around 50 mm thickness. For removing the entrained air and avoiding honeycombing and segregation, concrete should be stroked 35 times per layer for 150 mm cubes and 25 stokes for 100 mm using a tamping steel rod and then compacted by vibration using a vibrating table.

Compression test on concrete

Concrete will deteriorate and disintegrate and give indications of bad quality after few years even though concrete cube results were very satisfactorily. Conversely, a concrete structure constructed may be of good quality but the careless procedure for sampling, casting, curing, and testing of concrete cubes may give unsatisfactory results indicating low strengths.
