Standard Proctor Compaction Test

proctor compaction test

In this article named “Standard Proctor Compaction Test”,  the details and procedures of proctor test are described. Introduction For construction of highways, airports, and other structures, it is often necessary to compact soil to improve its strength.  Proctor (1933) developed a laboratory compaction test procedure to determine the maximum dry unit weight of compaction of …

Types of Foundation

strap footing

Foundation is a structural part of a building on which a building stands. Foundation transmits and distributes its own load and imposed loads to the soil in such a way that the load bearing capacity of the foundation bed is not exceeded. The solid ground on which the foundation rests, is called foundation bed. There are various types of foundation. …

Soil-Particle Size

Soil-Particle Size The sizes of particles that make up soil vary over a wide range. Soils are generally called gravel, sand, silt, or clay, depending on the predominant size of particles within the soil. To describe soils by their particle size, several organizations have developed particle-size classifications. Table 1 shows the particle size classifications developed by …

Piles: Situations Where You Need to Use Piles

concrete piles

Piles are structural members that are made of steel, concrete, and/or timber. They are used to build pile foundations, which are deep and which cost more than shallow foundations. Despite the cost, the use of piles often is necessary to ensure structural safety. The following list identifies some of the conditions that require pile foundations …

Determination of Soil Moisture Content

Moisture content measurement is mainly used to perform weight-volume calculations in soils. Also, moisture content is a measure of the shrink-swell and strength characteristics of cohesive soils. Test applied: ASTM D2216: Standard Test Method for Laboratory Determination of Water (Moisture) Content of Soil and Rock by Mass. Equipment and Materials: Oven-safe containers Disturbed sample of moist soil Scale …
