Reinforced Concrete Block Retaining Wall

For many years reinforced concrete masonry gravity retaining walls relying on gravity loads to resist the overturning forces due to soil pressure have been constructed using a reinforced concrete masonry stem steel reinforcement grouted into hollow concrete blockwork which is built on a reinforced concrete footing.

Reinforced concrete block retaining wall.

Reinforced concrete block retaining walls are a convenient way of building vertical retaining walls. Construction of concrete block retaining wall with steps excavation work for concrete block retaining walls. However let s compare two 8 inch thick walls. On the fourth course trowel a skim very thin coat of.

The block wall is reinforced with steel bars both vertically and horizontally. Strength of reinforced concrete sections amount of rebar a s the project calls for 5 10 and 5 12 are used. Consider the great wall of china for example where transverse bamboo poles were used to tie the walls together a forerunner of today s mechanically stabilized earth. Lay a run of masonry lathe down the entire course of the wall.

These walls consist of an engineer designed reinforced concrete footing to anchor the wall against overturning and a wall of concrete blocks filled with a concrete grout mix. Proper machines or tools should be selected and used for this. Mix the fill mortar slightly wetter than what you d use for joints. 2 5 clear to strength steel 5 12 rather than the designed 5 10 bending strength of the section has been reduced by about 16.

Stage 2 lay two row of block two block high with a 300mm gap in between the rows of blocks. The presence of reinforcing steel dramatically increases the overall strength characteristics of masonry or concrete. Stage 1 excavate and cast a reinforced raft. Foundation soil under the basement should be excavated.

Foundation soil preparation for concrete block retaining walls. How to reinforce a hollow concrete block wall step 1. Reinforced concrete would not be developed for a thousand years but they used what they had and learned how to do it better with each succeeding structure. Stage 3 pour concrete between the blocks to cast the reinforced concrete wall.

Lay your first four courses of concrete block wall. A reinforced wall either poured concrete or concrete block always contains some form of reinforcing steel. Strength reduced from 136 7 to 114 9 in kips. When you reach the finished height of the concrete block retaining wall fill those cores containing rebar to the top with mortar.

Spread additional mortar and lay cap block to finish the wall.
