The most necessary construction material - Aggregate


Aggregates are a raw material intensively used in construction of roads, bridges, streets, bricks, concrete, and tiles. Every town and city and every road connecting them is built and maintained with aggregates. Aggregates are mixtures of sand, gravel, crushed rock etc widely used in construction, as a component of concrete, and in civil engineering work. Most aggregates come from land-based sources, and developers rely on the best quality sources to supplement demand and meet the construction needs.

Delivering high quality aggregate to the construction industry, is a great challenge and is at the foundation of all infrastructure progress. Large volumes of aggregates add to the value and support the local economy.  They are also used to fill areas in ports and harbors or to reclaim land from the sea before the commencement of engineering works.

High-quality aggregate is popular in the markets. Aggregate Industries are witnessing an increased demand from all spheres and they need to increase their annual production capacity by several million tones. Geological Surveys emphasize the importance of aggregates. In order to build houses it takes several tones. At present there is high activity in many sectors, with regards to infrastructure and housing work around the big cities.

The country is also performing at all-time-high levels, and there is a constant fueling of demand owing to large infrastructure investments. The industry has witnessed large technological changes and has adopted new processes to meet the specifications of customers and dealers into operational level.

There is a stress to go for high quality products that are ideally suited to meet the customers’ needs. Moreover, what is required is a strong dealer network with excellent service support. The aggregate market holds lot of promise and is stable in production volumes. 

The activity is expected to go forward, as there is a considerable backlog in housing capacity. There is also a continuation of meeting the demands of people and that tends to mean more infrastructure projects turning into new tunnels, railways, subways and roads, and this leads to enhanced capacity.

In many areas of rapid population growth, the infrastructure is always inadequate, and new roads, streets and sewage systems are required to be built to meet the expectations and increased needs.

most asphalt pavements are  treated aggregates. The production of recycled aggregates, from concrete and asphalt pavements, has increased.

Replaced and reconstructed old roads and buildings have become a source of rich recyclable materials. In some applications, recycled aggregate has the potential to compete with newly mined aggregates on price and quality.

The production and utilization of natural aggregates is closely related to the population and the level of industrial development of an area. On an annual basis every person in the country requires 4.32 tons of crushed stone, 3.86 tons of sand and gravel 1/2 ton of cement.

During the past 20 years, per capita consumption of aggregates has increased by leaps and bonds.  An estimated 38,000 tons of aggregates are necessary to construct a mile of lane of an interstate highway.

Construction of an average modern home requires 400 tons of aggregate.

Construction of an average size school or hospital requires 15,000 tons of aggregates.

In using it we must remember that in order to maintain or improve our standard of living, we need to use all mineral resources judiciously. We must understand the environment and preserve natural resources for future generations.

Companies must meet the requirements of environmental regulatory requirements at all levels.

Concrete Curing Compound

Curing is essential for the hydration of cement in concrete making. So, to maintain required moisture content, come precautions are applied. Concrete curing compound is a compound which helps to prevent the loss of moisture content from the concrete. So, concrete is properly cured which results the full development of strength of concrete. Types of Concrete Curing Compounds ·          Synthetic Resin Concrete Curing Compound Synthetic resins will seal the concrete by forming membrane. If we want to provide plastering, the membrane can be removed by washing it with hot water. ·          Acrylic Concrete Curing Compound Acrylic is made of polymers of acrylic acid. It also seals the concrete in good manner. It is having property of adhesion to the subsequent plaster. No need to wash the surface of acrylic with hot water if we want to provide plastering. ·      ...

DESIGN PROCEDURES FOR A BUILDING FOUNDATION

Good design must not only be safe but must aim to save construction costs, time and materials. The following procedures should help to achieve this and an ‘educated’ client will recognize the importance of funding this work with a realistic fee. 1. DECIDE THE LOCATION OF COLUMNS & FOUNDATION AND TYPE OF LOADS ACTING ON THEM On the building plan, the position of columns and load bearing walls should be marked, and any other induced loading's and bending moments. The loads should be classified into dead, imposed and wind loading's, giving the appropriate partial safety factors for these loads. 2. ESTIMATE ALLOWABLE BEARING PRESSURE OF SOIL USING GROUND INVESTIGATION REPORT From a study of the site ground investigation (if available), the strength of the soil at various depths or strata below foundation level should be studied, to determine the safe bearing capacity at various levels. These values – or presumed bearing values (from any standards or codes) in the...

Parts of a Rock Drill

  Regardless of the industry, all types of rock drills have a standard design that is essentially a combination of replaceable attachments. The most significant parts of a standard rock drill include the following: ·          Drill bit : This is the tip of the rock drill that first makes contact with the ground during a boring operation. ·          Drill stem : This is the long frame that penetrates the ground during boring whose end houses the drill bit. ·          Drill rod : This is the hollow part of the drill stem that connects the motor of the rig to the drill bit. The drill rod is also responsible for transferring the cutting force to the drill bit to enable the rock drill to penetrate into the ground. ·          Carbide bits : These are special types of drill bits used in rotary and percussive drilling ...
