Abstract: In this experimental investigation, the strength of rapid hardening cement concrete paver blocks were evaluated by adding corundum powder as a mineral admixture in M35 grade concrete. Rapid hardening Cement (RHC) is a kind of cement which achieves strength very fast where the 3 days strength of RHC is equal to the 7 days strength of OPC cement with the same water-cement ratio and Corundum is a crystalline form of Aluminium oxide (Al2O3) typically containing traces of iron, titanium, chromium and small amount of silica . It is a rock-forming mineral which has the highest hardness and commonly used as abrasion resistant. Corundum is added to the concrete mixer.......

Keywords: Corundum, Rapid hardening cement, Compressive strength test ,Split tensile strength, Flexural strength test and Water absorption test of paver blocks.

Abstract: The road network in the Minapolitan area of Bantaeng which is a liaison between the nodes of production, processing and marketing has not been functioning optimally, hampered by the construction of two bridges that have not yet been connected. It is expected that with this study, it can be seen how the availability of infrastructure and facilities supporting the Minapolitan area and the strategy of developing road network infrastructure. The method used and samples according to Slovin formula, analysis of Location Quotient (LQ) to find out the base and non-base areas and SWOT analysis used for formulating a strategy for developing road network infrastructure, prioritizing the construction of bridges to connect the distribution of fisheries and marine products.

Abstract: Laterite formation is noticed about 70.7% in Konkan region. When laterite soil comes in contact with water it loses its strength. Use of biopolymers instead of other chemical compounds for soil treatment will develop a sustainable geotechnical system. The current study illustrates the potential of Xanthan gum polymer stabilized laterite soil. Xanthan gum in proportion 1%, 2% and 3% by mass is used for stabilization. For DST conducted on samples, cohesion increased by 35% and angle of internal friction decreased by 20% as we varied the xanthan gum content from 0% to 3%. The significant change in shear strength properties were observed for curing period of 3 days. The direct shear test was conducted using four different normal stresses of 0.5, 1, 1.5 and 2 kgcm2

Keywords: Biopolymer, Direct shear test, Laterite Soil, Shear strength, Xanthan gum (XG).
