Effect of Admixtures on the Compressive Strength of

Results showed that sawdust did not significantly enhance the compressive strength of sandcrete blocks. The results on the use of sugar showed that that sugar had a significant effect on the compressive strength of the blocks increasing it by 17% at 28 days. Both admixtures slowed down the setting and early stiffening of the mortar mix.

Analysis Of Sandcrete Blocks Production By Using Different

Sandcrete blocks comprise of natural sand, water and binder. Cement, as a binder, is the most expensive input in the production of sandcrete blocks (Hornbostel, 1991). This has necessitated producers of sandcrete blocks to produce blocks with low OPC (Ordinary portland cement) content that will be affordable to people and with much gain.

Enhancing the strength of sandcrete blocks using coarse

The sandcrete blocks developed 1.98, 2.10 and 2.21 N/mm 2 strength at 28 days for sandcrete blocks containing 5, 10 and 15% of coarse aggregates, respectively, as against sandcrete blocks containing 0% of coarse aggregates showing 1.86 N/mm 2. The percentages increase in compressive strength was 6.5, 13, and 18.8% for sandcrete blocks

Effect of the Portland

The commercial sandcrete block makers in Nigeria use the same cement-sand mix ratio for sandcrete blocks production irrespective of the cement grade. Investigation revealed that the compressive strengths of hollow sandcrete blocks produced with Portland-limestone cement grade 42.5 are higher than the sandcrete blocks produced with cement grade

Costs of Alternative Methods of Acquiring Sandcrete Blocks

cement, sandcrete block is made of only fine aggregate (sand) mixed with cement. The sand and cement mixture is in the proportion of 6:1 (British Standards Institution, 1970). Specifications for moulding sandcrete blocks stipulate that the block is generally to be made in accordance with BS 2028. Sandcrete blocks are made in three sizes in Nigeria.
