Geochemistry and Clay Mineralogy of Weathering and Soil Profiles, Malappuram District, Northern Kerala, India: Its Implications on Paleoclimate
Abstract: The present investigation chiefly concerns with the geochemical and clay mineralogical studies on two weathering and soil profiles at Pathirappadam and Ernadampadam in Nilambur valley, Malappuram district, Kerala. We attempt to understand the mobility of elements, weathering paths, and the common weathering products of gneissic rocks weathering on the western flanks of the Western Ghats. Our results indicate the depletion of Na, K, Ca, Mg and enrichment of Al and …

Improvement of Sand Subgrade Soil Strength with Geogride Reinforcement
Abstract: The quality and life of pavement is greatly affected by the type of sub-grade, sub base and base course materials. The most important of these are the type and quality of sub-grade soil. But in Iraq most of the flexible pavements are needed to be constructed over weak and problematic sub-grade. Flexible pavements constructed on weak subgrade with low California bearing ratio (CBR) are required to increase its total thickness. …

Development of a Mathematical Model for Assessment of Total Dissolved Salts
Abstract: The main purpose of this research is deriving a new equation which can be used to find the total dissolved salts (TDS) in the soil. This equation enables us to find the total dissolved salts (TDS) by finding density of the saline solution resulting from dissolving the soil in distilled water. This equation shows very good results. So, in this research a new method was proposed to find the total …

CBR Behaviour of Soil Treated with Class ‘F’ Fly Ash
Abstract: Disposal of fly ash available at thermal power stations is not only a serious national issue but also causes endanger to the mankind if not properly utilized and handled. The study aims at making effective utilization of Class ‘F’ fly ash by mixing with soil in suitable proportions and showcasing its usage to be adopted in subgrade as well as subbase components in pavement infrastructures. Silty sand was mixed with …

Bond Behavior of Reinforced Concrete using Artificial Sand with Quarry Dust as Fine Aggregate
Abstract: Reinforced concrete (RC) is most widely used material in the construction industry. Normally natural sand is used as fine aggregate in the production of conventional concrete. Natural sand is obtained from the river bed through mining operation. To fulfill the requirement of construction industry excessive mining of sand from river bed has been carried out. It is causing threat to the natural environment. Hence, Indian government has led down restrictions …

Mechanical Properties of Geopolymer Concrete Paver Block
Abstract: Geopolymer concrete (GPC) is an innovative material and a real alternative to conventional Portland cement concrete. It relies on minimally processed natural materials or industrial by-products to significantly reduce its carbon footprint. However, the development of this material is still in its infancy, and a number of advancements are still needed. This paper focuses on the production of geopolymer concrete paver block (GPCPB) without using sodium hydroxide and investigates the …

Soil Parameters Analysis of Al-Najaf City in Iraq: Case Study
Abstract: The soil properties are an important parameter for architectural and structural design of structures. Al-Najaf city in Iraq is a famous tourist destination, so in the last one decade a number of multistory buildings, bridges, highways, schools, hospitals, etc. have been constructed. This study investigates the properties of the soil to give a base data, which can be used for the future construction design. The physical and chemical soil properties …

Effect of Improvement of Collapsible Soils with Bitumen Emulsions on Collapsibility Rate for Varying Degrees of Saturation
Abstract: Collapsible soils are one of many problematic soils in Iraq. Many foundation failure problems that occurred in Iraq are associated with percolation of water; the change in the degree of saturation can affect the stability of these soils and may encounter large volumetric change. A series of tests conducted on collapsible soil using oedometer apparatus and the settlement–time curves are determined accurately, then each test is determined to a different …
