The Purpose and Make up of Concrete - 1340 Words

Concrete is an artificial stone-like material used for various structural purposes. It is made by mixing a binding material (as cement) and various aggregates (inert materials), such as sand, stone chips, brick chips, brick chips, pebbles, gravel, shale, etc with water and allowing the mixture to harden by hydration. There are many types of concrete available, created by varying the proportions of the main ingredients below. In this way or by substitution for the cementations and aggregate phases, the finished product can be tailored to its application with varying strength, density, or chemical and thermal resistance properties, Portland cement is the most common type of cement in general usage. It is a basic ingredient of concrete, mortar and plaster. Importance of Concrete some important of concrete are given below. Concrete is economical when ingredients are readily available. Concrete is a non-combustible material which makes it fire-safe and able to withstand high temperatures. It is resistant to wind, water, rodents, and insects. Hence, concrete is often used for storm shelters. Concrete could be requested in a variety of ways. It could be requested with a considerable measure of fly ash in the mix. Fly ash is a substitute for cement. In the present paper, the addition of fly ash and an expansive agent to the concrete of or a thin layer of fly ash to the interface between steel tube and concrete to improve the compressive strength.

The utilization purpose: Lightweight concrete can also be classified according to the purpose of utilizing as: i) Structural lightweight concrete has cylinder compressive strength at 28 days equal or more than 17 MPa and the approximate density range is about 1400-1800 kg/m3. ii) Masonry concrete (structural / insulating lightweight concrete) has a compressive strength between 7-14 MPa and density range 500-800 kg/m3. iii) Insulating concrete has a compressive strength between 0.7-7 kg/m3Read MoreLab Report On Concrete Of Concrete1284 Words   |  6 PagesConcrete SAMPLING: The first step is to take a test sample from the large batch of concrete. This should be done as soon as discharge of the concrete commences. The sample should be representative of the concrete supplied. The sample is taken in one of two ways: 1. For purposes of accepting or rejecting the load: Sampling after 0.2 m3 of the load has been poured. 2. For routine quality checks: Sampling from three places in the load. Concrete Slump Test: This test is performed to check the consistencyRead MoreCharacteristics And Applications Of Types Of Specialty Concretes : Watertight Concrete ( Wc ) And Self Compacting Concrete1354 Words   |  6 Pagesimprovement of modern architectural functions, higher requirements of concrete have been put forward. Under the circumstance of high technology, concrete technology is developed towards high-strength, high-workability and high durability. Since the 1990s, along with a variety of new cementitious materials, mineral admixtures, superplasticizer and the new development and application of other additives, the production of concrete with good workability, excellent mechanical properties and also high durabilityRead MoreAqueducts Of The Roman Aqueducts1395 Words   |  6 Pagesquestion whether aqueducts were better built than today’s bridges. The word â€Å"aqueduct† is Latin and comes from â€Å"aqua† and â€Å"ducere† meaning â€Å"to lead water†. The Roman aqueducts were a network of channels and pipes built above and below ground with a purpose to carry water across expanses of land. The concept of the Roman aqueducts is simple in theory as water seeks the lowest level of a slope – making it possible to run water down a gradual slant to a destination. The pipes used in aqueducts were mostlyRead MoreCement, A Fine, Soft, Powdery Type Substance1179 Words   |  5 Pages1.3.1. Cement Cement is a fine, soft, powdery-type substance. Concrete is a fine, delicate, fine sort substance. It is produced using a blend of components that are found in natural raw materials, for example, limestone, mud, sand and/or shale. At the point when cement is blended with water, it can tie sand and rock into a hard, strong mass called concrete. Cement is a binder, a utilized as a part of construction that sets and hard and can bind tie different materials together.

This aim can be fulfilled if the various concrete ingredients are relatively proportioned to yield an optimized result. In order to comply with ACI recommendations, strength tests are usually performed between 7 and 28 days after the concrete has been placed. This is time consuming and also experimental errors are inevitable because the rightRead MoreFundamentals of Building Construction: The Concrete1661 Words   |  7 Pages What is concrete? Concrete is a composite material used widely in the construction industry. Concrete is basically a mixture of cement, water, aggregates and admixture (sometimes). Cement is a fine gray powder that consists of oxidizes calcium, silicon and aluminum. The aggregate used is normally gravel, crushed stone or sand. Admixture is a solid or liquid substance that gives a certain characteristics of the concrete. The cement reacts with water chemically and binds the aggregates together
