Properties, classification and agricultural potentials of lateritic soils of Minna in sub-humid agroecological zone, Nigeria
Two pedons located on the Experimental Farms of the Federal University of Technology (EF) and Maizube Farms (MF) all around Minna were studied. The result indicated that the pedons had surface texture of sandy loam and sandy clay loam respectively overlaying fine textured subsoil. In the same order, the sand content ranged from 529 to 794 g kg-1 and 417 to 597 g kg-1 and decreased with soil dep...
متن کاملThe Effect of Rice Husk Ash on Mechanical Properties of Clayey Soils Stabilized with Lime in the Presence of Sulphate
Geotechnical engineers, in many cases face with low strength or high swelling potential of clayey soils. Stabilization methods are used to improve the mechanical properties of this type of soils. Lime and cement are the most popular materials used in chemical stabilization of clayey soils. If sulphate exists in the stabilized clayey soil with lime, or if soil is exposed to sulphates, problems s...
متن کاملElastic properties of fly ash-stabilized mixes
Stabilized mixes are used in the construction of bearing layers in asphalt and concrete pavement structures. Two nondestructive methods: resonant frequency method and ultrasonic pulse velocity method, were used for estimation of elastic properties of fly ash-stabilized mixes. Stabilized mixes were designed containing sand from the river Drava and binder composed of different share of cement and...
متن کاملUnique Properties of Volcanic Ash Soils
Various kinds of soils can be formed from volcanic ash depending on the individual set of soil forming factors at different sites. Among these soils, Andisols or Andosols show unique properties mostly due to abundant noncrystalline materials such as allophane, imogolite, Al-humus complexes, ferrihydrite and so on. Highly porous structures made of aggregated noncrystalline Andisol materials have...
متن کاملEffect of Stone Dust On Some Geotechnical properties Of Soil
Stone dust is a kind of solid waste material that is generated from stone crushing industry which is abundantly available. It is estimated that each crusher unit produce 15%-20% stone dust. Disposal of such wastes poses lots of geoenvironmental problems such as landfill disposal problems, health and environmental hazards. The best way to eliminate these problems is to make use such waste. Keepi...
