ECO-FRIENDLY BUILDING MATERIALS



Today many people that are building or remodeling their houses choose to use eco-friendly building materials. An eco-friendly building material is one that increases the efficiency of energy used and reduces impact on human well-being and the environment.

There are many different materials that can be used that are eco-friendly; from foundation, to insulation, to interior and exterior wall finishes, flooring, and countertop materials.

Why eco-friendly materials?
·         Phenomenal growth in the construction industry that depends upon depletable resources.
·         Production of building materials leads to irreversible environmental impacts.
·         Using eco-friendly materials is the best way to build a eco-friendly building.

ECO-FRIENDLY BUILDING MATERIALS
Stone quarrying leads to eroded hills, like this picture showing the site of makarana marble quarry, brick kilns in the fringes of the city lead to denudation of topsoil, dredging for sand damage the river biodiversity etc.

What is Eco-friendly material ?
Dictionary: describes a product that has been designed to do the least possible damage to the environment. US EPA – EPP program defines as: “products or services that have a lesser or reduced effect on human health and the environment when compared with competing products or services that serve the same purpose”
Thus we talk of two issues – one that it does the least possible environmental damage and two that it is a comparative scale as there are very few materials that are completely eco-friendly.

ECO-FRIENDLY BUILDING MATERIALS
One more point to note when we talk of eco-friendly construction is that it consist of two parts – Material and Technique.

A material by itself can be eco-friendly, e.g. Bamboo.

Or Even conventional materials can become eco-friendly based on the construction technique that is used. e.g. rat trap bond developed by Lauri Baker, which require less number of bricks and are more heat insulating than normal walls and therefore eco-friendly.

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 ...
