Compressive Strength of Hollow Concrete Block Masonry ...

The formula in EC6 for the characteristic strength of masonry calculated from the unit and mortar strengths does not agree with the results of tests already carried out in France on solid and hollow dense aggregate concrete units. For a hollow unit 100 mm wide with a compressive strength of 2.5 N/mm2 the formula gives wall strengths higher than the unit strength and further there is a ...

Mechanics of hollow concrete block masonry prisms under ...

01/03/2007  The paper addresses different relevant issues for the discussion of the mechanics of hollow concrete block masonry under compression, namely the shape of the stress–strain diagram, the deformation properties, the lateral deformations of the block, the failure modes and the need of an adequate effective Poisson’s ratio model for the mortar. In particular, it is advocated that the failure ...

Testing of Concrete Masonry Blocks for Compressive ...

Concrete masonry blocks are generally made of cement, aggregate and water. Which are usually rectangular and are used in construction of masonry structure. They are available in solid and hollow forms. The nominal dimensions of concrete masonry block vary as follows: Length: 400 or 500 or 600mm; Width: 200 or 100mm

Compressive Strength Prediction of Hollow Concrete Block ...

This paper discusses the results of a systematic experimental investigation on 306 stretcher bonded concrete hollow block masonry prisms under axial compression for the influences of block-mortar strength combinations, block geometry, height to thickness ratio (h/t) of block, mortar bedding, and thickness of mortar joint. The test results are then used to derive a prediction relation for a ...

16/11/2017  Because of the shape of the hollow blocks they will respond differently to compression compared to a solid block (the brick you mentioned). So before we talk about a formula (very difficult for hollow blocks) let us decide what you are actually testing for i.e. the aims of your project. You mention that you are going to incorporate different ingredients into your concrete mix. Presumababy you ...

Properties of Concrete Blocks — Strength

Actual tests of compression strength of hollow concrete blocks are difficult to make, because it is almost impossible to apply the load uniformly over the whole surface, and also because a block 16 inches long and 8 inches wide will bear a load of 150,000 to 200,000 pounds, or more than the capacity of any but the largest testing machines. Three one-quarter blocks, 8 inches long, 8 inches wide ...

Hollow Concrete Blocks: All You Need to Know

Hollow concrete block masonry is highly durable as the concrete is compacted by high pressure and vibration, which gives substantial strength to the block. Adequate curing increases the compressive strength of the blocks. 08. As the hollow concrete blocks are light in weight, they reduce the weight of the structure and hence light structural member or less percentage of steel is required for a ...

Concrete hollow block masonry is a common method used in civil and commercial buildings. However, inadequate brittleness, tensile and shear strength of concrete hollow block ma- sonry, especially the performance of masonry collapse and ductility under the action of earthquake, have seriously restricted the development of masonry structure. In this paper, the basic mechanical properties of ...
