· It prevents the direct contact of foundation concrete from the soil. It provides the protection of the main foundation from the soil below, because moisture or other chemicals in the soil such as sulfates can attack the concrete and weaken it.

How Important Is Soil Compaction In The Construction. Dec 20, 2013 0183 32 The dynamic compaction of the soil using different types of compaction machines has proven to be very efficient and effective method in construction To summarize, soil compaction is an important and significant process for any construction project and requires special attention and quality .
The use of RCB (obtained from the demolition of brick walls or waste bricks from construction sites) as aggregates is of particular interest because it helps to both reduce the solid wastes problem and preserve natural aggregate resources. The use of RCB as recycled aggregates has been considered by several research groups.
· The importance of horizontal flow patterns and bubble aggregation on the ability of dissolved air flotation (DAF) systems to improve bubble removal during drinking water treatment were explored using computational fluid dynamics (CFD) modeling. Both analytical and CFD analyses demonstrated benefits .
· The aggregates usually comprise 75% volume of the concrete. This percentage might give you the importance of these aggregates. One must be very careful in the selection of aggregates because the property of aggregates is basically the property of concrete. These are granular materials such as sand, gravel, crushed stone, or ironblast furnace slag.
· The significance and aim of this research study is to review the literature on the production and utilisation of recycled aggregate in roadway construction, concrete pavements, load bearing concrete structures and other civil engineering works and some discussion on the savings on CO2 emissions have been included.
During the concrete mix design, when the aggregate is to be batched by volume or by weight, then it becomes necessary to know the mass of the aggregates that will fill the container of unit volume. If we know the bulk density of the aggregate material then we can easily determine the mass required to fill a unit volume container.
· Aggregates are used in concrete to provide economy in the cost of concrete. Aggregates act as filler only. These do not react with cement and water. But there are properties or characteristics of aggregate which influence the properties of resulting concrete mix. These are as follow. Composition Size Shape Surface Texture Specific Gravity
Aggregates are an important part of any construction project. They provide the foundation for many structures and must be able to withstand pressure and weight. That's why it's important to test aggregates before using them in any construction project. There are a few different types of tests that can be performed on aggregates.
· Although aggregates are most commonly known to be inert filler in concrete, the different properties of aggregate have a large impact on the strength, durability, workability, and economy of concrete. These different properties of aggregate allow designers and contractors the most flexibility to meet their design and construction requirements.
· Coarse Aggregate is one of the most important and greatly used building materials in the Construction Sector. Coarse aggregates are mainly used in concrete, railway track ballast, etc. Requirements of Good Coarse Aggregate A good coarse aggregate should meet the following requirements: The shape is of the aggregate preferably cubical or angular.
The adequate capacity of mixing plant to field a mixture of proper and uniform quality. Quantities of various sizes of aggregate shall be fed in such proportions that the resulting combination follows the jobmix formula. To obtain a uniform distribution of the binder and the homogenous mix mixing time is should be the shortest possible.
· The Importance of Fineness Modulus Concrete Production Delivery Equipment, lab technicians perform a sieve analysis to determine the particle size distribution, or grading, of the aggregate sample, The higher the FM, the coarser the aggregate Fine aggregate affects many concrete properties, including workability and finishability ....
The strength of the aggregate cannot ensure the strength of the concrete. The strength of coarse aggregates are more important. of fine aggregates: Irregularly nodular shaped sand is preferable to completely round grained sand. The shape of the aggregate plays a more important role in the coarse aggregate than in the fine aggregate.
The importance of using the right type and quality of aggregates cannot be overemphasized. The fine and coarse aggregates generally occupy 60% to 75% of the concrete volume (70% to 85% by mass) and strongly influ ence the concrete's freshly mixed and hardened proper ties, mixture proportions, and economy.
