Learn More· The safe bearing capacity of soil should be determined on the basis of soil test data or by performing some field test such as Standard penetration test or Plate load test etc. However, in the absence of soil test data, the values of safe bearing capacity () as given in the following table may be used as a guide for preliminary analysis. Sl.
Learn More· Crushed stone: The term "crushed stone" usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.
Learn MoreEnvironmental characteristics include the nature and distribution of inorganic contaminants, such as metals and metalloids like arsenic, iron, and lead, in clay-bearing rocks. These environmental factors have the potential to affect the use of clays in natural and industrial applications. -

Learn MoreThe Unified Soil Classification System ( USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt ): If the

Learn More· Crushed stone with 100% fractured faces is your best friend. This is the best way to stabilize a soft area. Drainage would help but it may not be feasible to drain tight soils, so replace with crushed stone. The deeper the mudhole the bigger the stone. 100% fractured faces is key, bank run or river gravel that is rounded will not work very well
Learn More· Go along each side, marking the percentage of each constituent material, then draw lines down the tringle and see where the three cross over. If, for example, your soil sample has 50% sand, 20% silt and 30% clay, it would be described as a 'sandy clay loam'. If it was 70% clay, 20% silt and 10% sand it would be described as a 'clay'.

Learn MoreParticle size descriptions like sand, silt, and clay have specific meaning in geology and engineering. (see chart below). Shales, mudstones and claystones are rock types that are very similar to each other. Siltstone - greater than half of the composition is silt-sized particles. Claystone - greater than half of the composition is clay-sized
Learn MoreFine to medium sandy silty clay – 36 to 79% silty clay, 21 to 64% fine to medium sand. Clayey silt, trace fine sand – 90 to 99% clayey silt, 1 to 10% fine sand. It should be emphasized that a clayey silt has physical properties of a silt, not a clay, and a silty clay the properties of a clay. Often these two descriptions

Learn MoreClay minerals If a rock contains clay minerals, then an extra conduction pathway is possible via the electrical double layer that forms at the interface of the clay mineral and the water. This effectively allows ions to move through the system with a lower effective viscosity (higher mobility) than in the liquid phase.
Learn MoreTypes of soil: Soil can be categorized into sandy soil, silty soil, clay soil, peaty soil, saline soil, and loam soil. Following are the classifications. 1. Sandy soil: Among the different types of soil, sandy soil has the largest particles in it. It feels gritty and dry when touched and this is due to the huge spaces present between the
