B12 Construction Trading and Corporation Study on Quality Issues

The basic principle to remember is that concrete is a sloppy God-awful mess when we first look at it but then we turn it into something wonderful. We take the sloppy mud like concoction and

“Roman concrete (opus caementicium), like modern concrete, is an artificial building material composed of an aggregate, a binding agent, and water. Aggregate is essentially a filler, such as gravel, chunks of stone and rubble, broken bricks, etc. Binding agent is a substance which is mixed with the aggregate wet (water added) and solidifies when it dries, or "sets." Many materials, even mud, can be a binding agent, and used to make, what we generally call, mortar. Historically lime or gypsum, mixed with rubble stones, have been used as binding agents in making a strong mortar” (Roman Concrete).

First, concrete durable. Concrete is something that will outlive other products up to three times over (“What Makes…”). In addition to durability, concrete is efficient. Concrete can be made with byproducts from power plants, and other aspects of manufacturing. Concrete is primarily made up limestone, the most abundant material on Earth. Above all of this concrete can be recycled. Concrete can be crushed and recycled into another structure or product, reducing the need to mine the limestone for production. Concrete also allows water to pass through which reduces the chance of flash flooding, erosion, and water table depletion as compared to other materials. This is a major check in the sustainability of concrete; the conservation of soil, landscape and ecosystems. Concrete is a very green option when it comes to building

What is concrete. According to Concrete Network (1999) “Concrete is made up of three basic components: water, aggregate (rock, sand, or gravel) and cement. Cement, usually in powder form, acts as a binding agent when mixed with water and aggregates. This combination, or concrete mix, will be poured and harden into the durable material with which we are all familiar”. The Roman's did it a little

Concrete is used for many different things in daily life, although is often taken for granted. Concrete has a very deep history that leads us up to the modern day concrete and variations of. Most people will turn a blind eye, but at one point in history concrete was a stellar invention that had many different purposes and uses and still does today.

This is the most recent type of concrete formwork. It’s an emerging tech for RCC construction as well as architectural design work. This materials’ flexibility creates the ability to make concrete of any shape.

In order to discuss concrete; one must first mention cement. Cement is a water-based binder used to bind other building materials together. It is used in the production of mortar and concrete during the construction process. Concrete is a material used in construction, made by mixing aggregate, cement, small stones and water. Cement is important because it hold structures together. Many sources states concrete was invented 1756 by a British Engineer named John Smeaton. He did so by mixing pebbles as a coarse aggregate into a powdered brick into the cement. Years layer in 1824, a English inventor named Mr Joseph Aspdin created the first true artificial cement by burning ground limestone and clay together. He is also noted for creating today’s popular concrete; Portland cement. Many buildings use concrete because of its strong element. It solidifies then hardens after mixing with water and placement due to the chemical process known as hydration. Water reacts with the cement, which bonds the other components together, eventually creating a stone-like material. Concrete is used to make pavements, pipe, various structures, foundations, roads, bridges, brick walls and so on. It is either produced site-cast or pre-cast. Site-cast Concrete is standard concrete that is poured into site-specific forms and cured on site; the concrete is created on the actually construction site. Precast concrete is a construction

Roman concrete, called opus caementicium [o-pus see-men-tic’-ee-um], was made with a special Roman mortar or cement, called caementa [see-ment’-a], created by mixing water, lime, and a special volcanic ash sand, called pozzolana, that gave Roman caementa its special strength. Roman concrete [opus caementicium] was created by first building a form and then pouring in alternating layers of the Roman caementa and layers of rocks, bricks, or gravels. As each layer of rocks, bricks, or gravels was poured in and spread around, Roman workers would then pound the layers firmly together with a tool called a tamp. Roman cement was special not only because it was strong but because it was also hydraulic—it would set up and harden even under water, which made it handy for building things like Roman sewers, cisterns, baths, and even

Aggregate is one of the basic constituents of concrete. Its quality is of considerable importance because about three-quarter of the volume of concrete is occupied by aggregates. One of the physical properties of aggregate that influence the property of concrete is the grading of aggregate. The grading of aggregate defines the proportions of particles of different size in the aggregate. The grading of fine (size < 5 mm) and coarse (size > 5 mm) aggregates are generally required to be within the limits specified in BS 882: 1992.

The definition of high strength changes over the years as concrete strength used in the field increases. Any construction activity requires several materials such as concrete, steel, brick, stone, glass, clay, mud, wood, and so on. However, the cement concrete remains the main construction material used in construction industries. For its suitability and adaptability with respect to the changing environment, the concrete must be such that it can conserve resources, protect the environment, economize and lead to proper utilization of energy. To achieve this, major emphasis must be laid on the use of wastes and byproducts in cement and concrete used for new constructions. The utilization of recycled aggregate

Constructions project management involves the direct and daily monitoring of all construction activities and tasks, including all the construction methodologies that is being applied, as well as the personnel that directs or guides the project through every single stage or phase of its life cycle. It is pertinent to know that not all constructions jobs might not be successfully completed due to some changed conditions or unforeseen circumstances beyond control like the effects of nature and differing site conditions. Some of the constructions projects get rejected or are abruptly cancelled due to reasons best known to either the contractor or the client as the case maybe, but whatever happens regardless. Proper and effective closure is always needed on all constructions projects.

T&T Co. is a Cochin-based private construction and Architecture Company, established in 1995 mainly undertaking projects concerning building and bridge constructions. The company is headed by a board of directors, led by Mr. Thahir C.A. The head office of the company is situated in Aluva, Cochin district of Kerala.

The construction industry is among the most contributing industries in any economy. This has made the construction industry very competitive and major construction firms are improving on their strategic plans in order to gains competitive advantage.
