Demand for natural sand in concrete is increasing day by day since the available sand cannot meet the rising demand of construction sector. This paper reports the experimental study undertaken to investigate the influence of partial replacement of cement with Ground Granulated Blast Furnace Slag(GGBFS) in concrete containing quarry dust as fine aggregate. The cement was replaced by 10%, 20%, 30%, 40% and 50% of GGBFS and tests were conducted to determine the optimum level of replacement of GGBFS in quarry dust concrete. The specimens were subjected to compressive strength, split tensile strength, flexural strength, and bond strength tests at 7days, 28days, 56days, 90days and 150 days. The resistance to corrosion is evaluated based on the performance of the concrete for the penetration of chloride ions by means of impressed voltage technique in saline medium and Gravimetric weight loss method. Results herein reveal that an increase in slag proportion increases the strength properties and decreases the rate and amount of corrosion of reinforcement and among the various percentages of replacement 40% is found to be optimum with better strength and corrosion resistance properties.

Problematic Soil

This study was carried using finite element software (Plaxis) in studying the Engineering behavior of erodible soil-quarry dust composite at a proportion of 50% quarry dust and 10% cement. It discusses the effects of decorative street light through numerical analysis using the Finite Elements Method. Plaxis program v8.2 was applied to model the soil behavior. The Mohr-Coulomb model reveals that the deformations are concentrated exclusively on the base course, with the appearance of plastic tension cut-off points on base course. The structure was subjected to double point loads of 50 kN/m each which resulted to 100 kN/m. The results shows that the pavement deformed at load 85.16kN/m which showed that the soil strength cannot withhold the pressure from the street light. The load displacement acting on the base of the highway in study is . The result also shows that failure was concentrated at the base course of the pavement. This was due to the presence of underground water beneath the phreatic level. The quarry dust is a good replacement to weak soil or a good additive to help improved a problematic soil. From analysis, the soil strength lies below the effective stress acting on the pavement which is equal to 85.16 kN/m. It is advisable to replace some quantities of the existing soil and be replaced by quarry dust since quarry dust is a waste product from crushing of stones. Lastly, about 30% of the existing soil should be replaced by either the mixture of lateritic soil and quarry dust or the soil there should be used as subbase which may not be economical.

Effect of spent calcium carbide (SCC) on index and strength properties of lateritic soil at differ- ent compactive efforts was assessed in this study as potential means of improving the geotechnical properties of the subsoil as well as disposing of SCC as waste. SCC was admixed with the soil using 0 to 10 % by dry weight of soil at an incremental rate of 2%. The following tests were carried out on the samples: specific gravity, Atterberg limit, particle size distribution, compaction, and California bearing ratio (CBR). Compaction and California Bearing Ratio (CBR) tests were carried out using British Standard light (BSL), West African Standard (WAS), and British Standard heavy (BSH) on both the natural and stabilized soil samples. From the investigation, atterberg limits show a reduction in the plasticity index with increasing content of SCC. The maximum dry density of the soil decreased with increasing SCC content and increased with an increase in compactive energies (BSL<WAS<BSH), while and optimum moisture content (OMC) increased correspondingly. Also, soaked and unsoaked CBR values of the stabilized lateritic soil showed an increase in strength with higher compactive effort, and SCC content up to 4% SCC addition and after that decreased in value. Based on these results, spent calcium carbide improved the geotechnical properties of this lateritic soil, and 4% SCC is recommended for its stabilization as subgrade material for pavement construction, thereby serving as an effective method of disposing SCC towards promoting a green and sustainable environment.

Concrete is an important construction material widely used in the construction industry nowadays. It is blended material consisting of cement, fine aggregate, coarse aggregate and water. Generally the use of river sand as fine aggregate in our country is very widespread in industry. This paper mainly focuses on the study of strength properties of concrete in which river sand is replaced with sea sand as fine aggregate. In addition to it, Quarry Dust when added gains strength. Different mix proportions was replaced partially in 5%, 10%, 15% by Sea sand and Quarry dust. The strength of concrete for various mix proportions are carried out and tested for 14, 28, 56 days of curing. From the results obtained, with the replacement of river sand by sea sand along with well graded quarry dust upto to 15% increases the strength of concrete.
