What’s the difference between concrete blocks and breeze blocks?

A concrete masonry unit (CMU) is a standard-size rectangular block used in building construction. Those that use cinders (fly ash or bottom ash) as an aggregate material are called cinder blocks in the United States, breeze blocks (breeze is a synonym of ash) in the United Kingdom, and hollow blocks in the Philippines.

Is breeze block as strong as brick?

Both concrete blocks and bricks are relatively strong, but the efficacy of this strength is helped and/or hindered by the quality of the mortar that is used to hold them together in construction. The former can withstand 3,500 psi, whilst bricks’ limit is found at 3,000 psi.

Are breeze blocks porous?

It’s a losing battle – cinder blocks are water permeable! Exterior, above-grade cinder block walls (retaining walls, decorative walls) are not subject to hydrostatic water pressure complications.

Why do cinder blocks have holes?

The openings are called “cells” and one reason they are there is because they make the blocks lighter and easier for a mason to handle. But the primary purpose of the cells is that they align from top to bottom of the wall when laid, and enable a builder to fill some cells with grout/concrete to strengthen the wall.

Why bricks are preferred over blocks?

Ideally, between bricks and blocks, blocks would get the work done faster because blocks covers a bigger area than a brick. Thus, it falls to reason that one will need fewer blocks compared to bricks. That translates in lower labour costs because the masons and helpers will take a shorter duration on the site.

Why are breeze blocks used?

Breeze blocks allow for ventilation but also provide some privacy and sun protection. Another bonus is they are structural so they can be used in place of framing for support. The use of breeze blocks is making a huge comeback as an architectural element for its ornamental look and vintage vibe.

Can breeze blocks get damp?

Blocks/bricks are porous. The external wall can get very wet, whilst the internal wall remains completely dry, due to them being separated by the cavity.

Can you use wet breeze blocks?

Do not wet the blocks before installing them. Wet blocks expand, then shrink when they dry. If it rains or rain threatens, cover the blocks.

Should you fill cinder blocks with concrete?
