Deep foundations can be made out of timber‚ steel‚ reinforced concrete and prestressed concrete. Development: I- When do we need pile foundations: · Top layers of soil are highly compressible for it to support structural loads through shallow foundations. · Lateral forces are relatively prominent. · In presence of expansive

machine saled in vipeak Sand washing machine or sand washing plant is widely used in particle aggregate sand screw washing‚ grading and dehydrating quartz and sand in construction site‚ sand stone factories‚ hydropower station and concrete dam site‚ precast concrete factory‚ glass factory and etc‚ so that sometimes it can also be called mineral sand washer. During the sand making process‚ the bucket sand washer has wide application due the strong market demands of artificial sand in the construction

I. Introduction Aggregates contribute to 60-80% of a concrete mix‚ with water and cement being the other major constituents. Therefore considerable testing and consideration should be placed on aggregate type and size to ensure an adequate concrete mix. Two tests have been performed to establish the properties of the aggregates: 1. Compacted bulk density test 2. Sieve analysis II Testing For Compacted Bulk Density Objectives * To determine the specific bulk densities of a range

middle layer‚ called the pavimentum‚ is crafted with gravel or sand. The second to top layer‚ known as the radus‚ is made with fine concrete. The top layer‚ called the summum dorsum‚ is made with flat stones and concrete. Our modern roads are made with crushed rock‚ known as arggregate‚ at the bottom. Then there is the base‚ which is a huge layer of concrete in the middle. Lastly‚ there is the pavement‚ called the super pave‚ at the top. Both Roman roads and modern roads have had many uses

areas are shown in Figure. Even if two surfaces have a similar albedo‚ the incident energy does not always result in similar temperatures because the thermal capacity of those surfaces may differ. Concrete‚ which is used as construction material extensively all around the world‚ has many benefits. Concrete has an albedo value ranging from 0.1 to 0.35. These values are higher than those of some other materials‚ and it is also lighter in colour. Factors that cause a higher temperature in urban areas:
