The mechanical properties of lime concrete

Abstract EN

Lime concrete shall be prepared by mixing coarse aggregate and lime mortar in the specified proportions with required quantity of water.

Lime has been used as a cementing material since times immemorial.

The influence of hydrated lime Ca〖(OH)〗_2 on the 7, 28 and 56 days compressive and splitting tensile strength also 28 day density tests were investigated.

Results indicated that all mixes specimens exhibited continuous strength gain.

The defects in lime concrete, particularly its slow setting compared with that of cement concrete could be got rid of by adding to it a definite proportion of cement.

Result showed that the 28 – day compressive strength of lime concert mix was 4.8mpa, while the 28 day compressive strength of cement concert mix was 28.7mpa with the same mix proportion.

At 28days of curing, the Percentage increase in compressive strength of lime- cement concert mix relative to lime concert mix was 70%.

Lime concrete have some advantageous properties e.g.

good workability and plasticity, lime is cheaper too and is locally available.
