Introduction. The increasing demand for environmentally-friendly materials necessitates cheaper construction materials [1-3]. Quarry dust (QD), regarded as a waste material, …
The effect of quarry dust-based geopolymer cement on the compressive strength, erodibility, and durability potential of expansive soils has been studied under laboratory conditions. The particular interest was on the geopolymer cement treatment of soils subgrade under hydraulically bound environments. Lateritic soils, which form the …
The average water absorption value for quarry dust from Abuja and its environ was 0.96%. It falls within the AASHTO, recommended range of 0.2% to 2% (ASTM, 2012). Workability of concrete depends ...
The specific gravity of materials namely: laterite, quarry dust and coarse aggregate were found to be 2.56, 2.67 and 2.71, respectively. The values are in agreement with the results of Udoeyo et al., [21] and Ilangovana et al., [22]. Similarly, bulk densities of laterite, quarry dust and coarse aggregates were found to be 1460, 1230 and 1830Kg ...
The quarry dust is obtained as an aggregate waste, during crushing of rubble to obtain aggregates . Sabat and Das ( 2009 ) had stabilized expansive soil using quarry dust and lime for
The following conclusions can be made from this study: i) The following physical properties of laterite, quarry dust and granite chippings were investigated, namely: specific gravity, density and particle size …
Quarry dust (QD), regarded as a waste material, could also provide a stabilizer for laterite cement blocks. QD is a waste that is obtained during the quarrying process. According to Febin [4], manufactured sand constitutes 30-40% QD.
The quantity of laterite was varied from 0% to against quarry dust at intervals of 25%. The samples were cured for specified periods and tested in the laboratory for compressive strength. Workability tests were earlier carried out to determine the optimum water/cement ratios for three different mixes, namely: 1:1:2, 1:1.5:3 and 1:2:4.
The use of laterite stabilized with cement using quarry dust as additive for use as base course material was investigated. The laterite soil used was an A-2-6 and GP soil using AASHTO and USCS ...
Quarry dust which is a waste product from aggregate crushers could replace sand. Construction of pavements in expansive soils creates a lot of problems for civil engineers, stabilization with ...
Abstract. This study investigated the prospect of utilising red earth, quarry dust and laterite as alternative materials to river sand in the production of sandcrete …
Test results generally indicated that the addition of quarry dust and lime to an amount not exceeding 5% quarry dust and 5% lime improved the suitability of the laterite soil as a subgrade amount. Therefore, 5% optimal stabilization of the A-2-4 soil effectively improved the suitability to meet the requirement for use as subgrade course materials.

The stabilization method has to be safe. In this study quarry dust (QD) in proportions of 5%, 10%, 15%, and 20% and lime in proportions of 1%, 3%, and 5% were …
The stabilizer used was ordinary portland cement which conforms to BS 12 [27]. 134 ONYELOWE, KEN C. et al., W J Engg Sci, 2013; 1(4): 133-143 Figure 1: Map location of sample site. ... This is due to the reduction in laterite as the quarry dust content increases, and the addition of quarry dust does not require more water for any reaction other ...
Volume 2, 15 December 2021, 100023. Effect of micro sized quarry dust particle on the compaction and strength properties of cement stabilized lateritic soil. RolandKufre Etima, …
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 quarry dust and lime were mixed with locally available lateritic soil to examine the improvement in the geotechnical properties in developing better subgrades for rural …
The highest MDD occurred at 20% Quarry Dust and 5% cement with an MDD value of 1410kg/ when both additives were combined. Summary of California bearing ratio test results of quarry dust as a ...
On adding quarry dust to BCS in increasing amount, the liquid limit of the composite reduced from 71 to 50%, and plasticity index reduced from 40.6 to 25.5% with 24% quarry dust content (Fig. 4). The reduction in liquid limit on adding quarry dust may be attributed to the inclusion of bigger particles of quarry dust into BCS.
[49], observed through his study on the geotechnical properties of saw dust ash stabilized Southwestern Nigeria lateritic soils that the linear shrinkage, natural moisture content, optimum ...
This study investigates the effect of stabilizing laterite using quarry dust and limestone powder to improve the geotechnical properties. The soil sample was …
To date, the instability, as well as the strength of laterite soils in the construction application, has been widely addressed by many scholars. One of the main strategies to improve the laterite soil's characteristics is to utilise an effective soil stabiliser (i.e., chemical stabilisation). Previous studies have shown that the strength of the laterite …
prepared using 70% laterite soil and 30% of cement has been. compared with specimens in which cement is replaced with fly. ash and quarry dust in ranges of 10% and 2 0% of its weight. The. 28 days ...
The F1 ionic soil stabilizer significantly reduced the pore size and area of red clay, the complex connected pore structure is adjusted to a more regular structure. The reinforced clay had 56.64% ...
