Standard Proctor compaction test The object of this test is to determine the relationship between the water content and dry density of soil and also to determine the optimum moisture content corresponding to maximum dry density. Laboratory compaction test; Standard Proctor compaction test of soil are described below Test Apparatus The Apparatus used for this place … Continue reading Laboratory compaction test- Standard Proctor compaction test of Soil
Degree Of Compaction The ratio of the field dry density (determined by core cutter or any other method )to the maximum dry density determined in the laboratory (by Proctor apparatus) is Called degree of compaction. Degree of compaction = Field dry density / maximum dry density determined in the laboratory. For non-cohesive soil, it … Continue reading What is Degree Of Compaction, Optimum Moisture Content and Compacting Effort -Soil
Suitability Of Various Compaction Equipment a) Smooth wheeled rollers are most suited for compacting crushed rock, hard core, mechanically stable gravel, and sand. They also give satisfactory results for moderately cohesive soils. b) Vibrating-type equipment, crawler tractors, and rubber-tyred rollers are effective for compacting cohesionless sand and gravels. c) Sheep-foot roller is another heavy equipment … Continue reading Suitability Of Various Compaction Equipment

Factors Affecting The Compaction Of Soil 8 Factors that affect the performance of compaction are as follows:1. Type of compaction.2. Compacting effort.3. Type of soil.4. Uniformity of soil water mixture.5. The particle size distribution of the soil sample.6. Moisture content in the sample.7. Original soil condition8. Addition of admixture. Type of soil The maximum dry … Continue reading 8 Factors Affecting The Compaction Of Soil
Role of Water in Compaction Of Soil Water plays an important role in compaction. When water is added to dry soil, the soil grains get surrounded by a film of absorbed water. If more water is added, then this becomes thicker and soil grains surrounded by such films can slide over each other more easily. … Continue reading Role of Water in Compaction Of Soil
8 Importance of Compaction of Soil The process of compaction changes the characteristics of the soil mass in the following way: 1. Improves the dry density of the sample.2. Increase the cohesive value of the sample. 3. Increase the angle of internal friction.4. Improves shear strength of soil mass. 5. Reduces the shrinkage and compressibility.6. … Continue reading 8 Importance of Compaction of Soil
