These mix ratios are used as a rule of thumb in Nigeria irrespective of their strength. 5.1 Compressive Strength Test and Cost of 1m3 of Concrete. Concrete cubes of 150mm were moulded for both river sand concrete and laterite-quarry dust concrete in accordance to BS EN 12390-1 (2000) and tested for their compressive strength (fc).

It was also observed from the results that the workability of laterite concrete (LATCON) increases with increase in the replacement level of sand by laterite, while the compressive, split tensile, and flexural strengths and the percentage water absorption of the concrete decrease with increase in the replacement level of sand. III.

Concrete mixes containing 0%, 10%, 20%, 25 % and 30%, replacement (by weight) of fine aggregate with quarry dust and simultaneously 25% replacement of coarse aggregate (by weight) with laterite stone were casted in lab and checked for compressive strength, split tensile strength,flexure strength and workability .This replacement results in ...

In this work, the feasibility of the usage of quarry dust as 60:40 proportion of substitution of natural sand i.e (quarry dust replaces 60% of natural sand) in concrete. Silica fume is added as mineral admixture by 15% of weight of cement and steel fiber used in different percentage (0.5%, 1.0%, and 1.5%) to increase the tensile strength.

quarry dust concrete is 10-12% more along with durability under sulphate and acid action. It also shown that the water absorption property of this concrete is slightly higher and lastly they have conclude that the replacement of natural sand with quarry dust, as full replacement in concrete is possible. To decide the water content and mix ...

This is part of a research on the structural characteristics of concrete using lateritic sand and quarry dust as fine aggregate. This paper presents the results of an experimental study investigating the flexural and tensile characteristics of concrete using combinations of lateritic sand and quarry dust as complete replacement for conventional river sand …

It therefore seems that the optimum w/c for 1:1.5:3 mix is somewhat between 0.5 and 0.6 while the recommended percentage of laterite in laterized quarry dust concrete is 20%. Nigerian Journal of Technology E. E. Ambrose, et al Figure 4: Variation of 28th Day Compressive Strength with Water/Cement Ratio at Different % of LS (1:1.5:3 mix) 4.

The results showed that river sand and quarry dust with a compressive strength of 10 to 30% replacement is an excellent construction material for constructing concrete. ... quarry dust and river sand are suggested as construction materials for making concrete, and can be used to replace river sand up to 30% of the time to …

The blocks comprised of different percentages of laterite soil (76%, 81%, 85% and 87%), quarry dust (9% and 10% by weight of the soil) and ordinary Portland cement (3%, 5%, 10% and 15% by weight of the soil. The results showed that cement content of 10% and 9% quarry dust was suitable for the block at any curing period above 7 days.

Laterite and sawdust wastes can be used as partial replacements for sand and cement in concrete. The concrete produced has improved strength, reduced …

This paper is part of a study investigating the structural characteristics of concrete using various combinations of lateritic sand and quarry dust as complete replacement for conventional river sand fine aggregate. Samples of concrete (eg. cubes) were made using varying contents of laterite and quarry dust as fine aggregate. The quantity of laterite …

This study investigated the prospect of utilising red earth, quarry dust and laterite as alternative materials to river sand in the production of sandcrete blocks. …

Since lateritic sand and quarry dust are waste in environment they can be disposed by using in structural concrete. Lateritic sand and quarry dust were varied at different proportions. Fig 3. Flexural strength of concrete mixes for 28 days curing in N/mm2. Trial mix design was carried out for different W/C ratios.

The compressive strength of cubes at 28 day curing for control mixture of 1:3:6 at 0% partial replacement of river sand with quarry dust was 12.6N/mm 2 but compressive strengths of 21.5 N/mm 2 and ...

By exchanging some of the sand in concrete for quarry dust, compressive strength can be measured for a range of percentages and grades of the material.
