Concrete technology is the study of the properties and applications of concrete in construction work. It requires an understanding of materials that make up concrete which are fine and coarse aggregates, cement, and water. Concrete technology is a broad area of study in engineering. To complete concrete technology assignments, students are required to acquire knowledge and understanding about an exhaustive list of topics such as cement, aggregates, mineral and chemical admixtures, concrete and fresh concrete, dimensional durability and stability, engineering properties of concrete, and so on. Concrete Technology Assignment help experts students to gain an understanding of concrete, its ingredients, and properties in construction work. It also includes some of the basic elements of roadways construction, fracture machines, non-destructive testing in concrete technology, and developmental trends of concrete.

What do you Understand by Concrete Technology?
Concrete is a type of building material made up of coarse and fine aggregates, cement, or sand blended with water which solidifies over the period. To manufacture concrete, Portland cement is used and it is the most common form of cement for manufacturing. The study of concrete technology controls the properties of concrete and its use in the building. During the construction of buildings, concrete is utilized for the building of beams, columns, slabs, foundations, and other load-bearing. To construct the road, asphalt concrete uses lime concrete, lime, and bitumen as its binding material.
There are several forms of cement which are utilized for concrete tasks. They have several applications and properties. A few of them are rapid hardening cement, Portland pozzolana cement, sulfate resistant cement, and others. The ratio of water-cement plays a significant role which improves several properties like strength, workability, and durability. Concrete could be reformed into any shape. In fresh state concrete is a plastic material, it is used to provide various shapes like circular and rectangle. Additives or admixtures like superplasticizers and pozzolans are incorporated in the mixture to enhance the physical properties of the finished elements and wet mix. Hoover Dam and Panama Canal are famous and large structures constructed using concrete
What are the Different Types of Concrete Construction?
The two most common types of concrete are used for building works and construction.
Plain Concrete Construction
This can be cast and poured in the absence of any reinforcement. PCC is utilized when the constructional component is strained only to the compressive forces and not bending.
Reinforced Concrete Construction
What Are The Basic Steps Of Construction Using Concrete?
- Choosing amounts of constituents for chosen mix proportion
- Looking after workability
- Pouring in the model for casting
- Vibrating for accurate compaction
- Discard the model after an appropriate period
- Curing member with appropriate techniques and accurate period
Building Blocks of Concrete
Cement, water, sand, and aggregates are building blocks of cement. The blending of water and Portland cement is known as a paste. Hence, concrete is often known as a blending of aggregates, sand, and paste. Very often rocks are utilized in place of aggregates. The form of cement coats the surface of the coarse as well as fine aggregates when blending properly and blends them. After blending with the building blocks of concrete, a hydration reaction begins which gives a rock-hard concrete, and strength is formed.
How Concrete is Made?
Concrete is formed or blended within ratios concerning cement quantity. The most common types of concrete mixes as discussed below.
Nominal Mix Concrete
It is utilized for normal building purposes like small residential construction. The most known mix concrete is in the proportions of 1:2:4.
Designed Mix Concrete
It is used for those purposes for which mix ratios are set depending upon several lab tests like cube or cylinder for its compression strengths. This procedure is known as mix design. Lab tests are performed to identify appropriate mix depending upon regionally available components to retrieve strength needed as per constructional format. Designed mix concrete offers economy on utilization of materials.
After accurate mix proportions are defined, then its components are blended in the proportions as chosen. Hand mixing and machine mixing are two methods used for mixing. Depending upon the quality and quantity needed, the appropriate technique of blending is chosen. During hand mixing, every component is emplaced over a flat spring, and water is added and mixed with hand devices. During machine mixing, several forms of tools are utilized. In such a case, the components are taken in suitable quantities to blend and synthesize fresh concrete. Once formwork is removed, curing is done by several techniques to make up the moisture because of evaporation. Moisture is needed for hydration reaction which is accountable for strength gain and setting. Hence, curing is commonly perpetual for a minimum of 7 days once falsework is removed.
