Cohesiveness is affected Aggregate grading and water content. c) Strength Strength of concrete is usually determined in terms of compressing strength. In cases where strength in tension or in shear is of primary importance the compressive strength is frequently used as a measure of this property. Factors affecting strength of concrete are as follows: • Water cement ratio: the strength of concrete depends upon strength of cement paste, & strength of cement paste depends upon dilution of paste. • Aggregate cement ratio :The strength may vary from different aggregate cement ratio.
Concrete materials are still a dominant material for construction due to its advantages suchas workability, low cost and fire resistance as well as its low maintenance cost. It is formed from a hardened mixture of cement, fine aggregate, coarse aggregate, water and some admixture. Massive exploration of the natural resources for producing concrete affect to the environment condition and global warning. We have responsibility to reduce the effect of the application of concrete materials to environmental impact. The concrete should be used as efficient as possible.
The correlation between the NDT and the structure strength can be established. The correlations are particular for a certain type of concrete and must be used with caution. Concrete properties can vary considerably depending on the nature and proportions of its materials, the construction methods and the loading and environmental conditions. In order to prevent and control the concrete deterioration, it is interesting to establish continuous monitoring strategies, which might be a powerful tool to increase the service life of concrete. This implies the development of control methods which are able to determine the quality and the condition state of concrete.
Not only does it make them aesthetically pleasing, but it also keeps them safe. Make sure you regularly power wash your concrete with water. Additionally, make sure you remove anything that is piling up on your concrete such as snow, ice, rotting leaves or grass, and
The wet concrete is then placed and spread over the reinforcement and the formwork. It is compacted, vibrated and leveled off. Steel reinforcing bars are cast into the underside of the floor with 20mm or more concrete cover below them to prevent the steel rusting and to give it protection in case of fire. The thicker the concrete cover to reinforcement, the greater the resistance of the floor to fire. A combination of high tensile steel and mild steel reinforcement is used.
The most important factor in curing concrete is to promote action to ensure enough water for the entire cement chemical reaction process is complete. An uncured concrete or poorly cured, can have a strength up to 30% lower, besides being very vulnerable to aggressive agents, due to the large amount of cracks
Reinforced concrete is stronger than most of the other materials used in the construction industry. Apart from providing great strength it also has good tension capabilities. The materials have a longer lifespan and the maintenance cost is also lesser. For constructing larger structures such as dams reinforced concrete is very economical and can save lots of money for the builder. They can take any shape and is used in making structural components before casting.
Sand which is locally available and is free from any organic impurities is used. Which is further passed through IS sieve of 4.75 and retained on 150 micron IS sieve is used in the making of the concrete. The physical properties of fine aggregate like fineness modulus, specific gravity and Bulk density are tested in accordance with IS S.no Test Observations 1. Fineness Modulus 2.73 2. Specific Gravity 2.65 3.
The mechanical properties of concrete determined in the laboratory include compression strength, splitting tensile strength and flexural tensile strength. The influence of partial replacement of fine aggregates by copper slag on the compressive strength, split tensile strength on cylinders and flexural strength of prisms has been evaluated. The test results showed that there is a possibility of use of copper slag as fine aggregate in
This is apparent as even modern definitions of interior design state that its elements are in fact closely related to architecture. Experienced interior designers and architects both employ scientific as well as artistic skills to qualify in creating or designing spaces that solve problems or meet the requirements of building owners and that is done through spatial design and planning. The spaces created should be pleasingly structured, safe and functional. Generally speaking, Architects and interior designers creative and artistic individuals who usually have cross-over skills, namely space-planning, are up-to-date with a state’s building codes and regulations and closely examine materials, finishes, furnishings and cabinetry to make sure they are the right fit for the client and for the home itself. At times the job of architects overlaps with that of interior designers as they both select the tile, flooring and lighting and design the look/style of a home’s interiors.
