Introduction:
Concrete : The word concrete comes from the latin word “concretus” (Meaning compact or condense) . Concrete is made by mixing (Cement, Water, Course and fine aggregate, admixture as required)
The main theme of our project is to determine the compressive strength of concrete specimen under the implementation of cold and hot water curing.
As cold and hot water effects concrete in different ways which will be further tested and analyzed on the basis of various previous researches, and also will be examined practically.
PROBLEM STATEMENT
The study will focus on the effects of both cold water and hot water curing (extreme conditions) as well as on normal circumstances .
Hydration, sometime in cold weather is difficult to maintain

METHODOLOGY
Data Collection:
Data to be collected for research from the following sources:
Books
Relative reports.
Published related articles.
Research reports relative to the above mentioned research work.
Practical Work: For practical work on this project we will use ordinary Portland cement and will produce different specimens of concrete. The specimens will be cured at cold and hot water for different period of times in cold and hot water separately. After the complete curing period, the specimens will be crushed in Universal Testing machine to obtain the required results. These tests are performed to

they're not. Concrete is to cement as a cake is to flour. Concrete is a mixture
At first the Romans did not realize the superior ability of concrete. They began by using it as a fill. They would also cover up the concrete with decorated stones. The concrete they used did not look pleasing because they had mixed it with any arrogate they had available. Later, once they discovered how useful concrete could be, they used it for everything they could. They built their houses, roads government offices, theaters, temples, and everything else they could out of concrete. Concrete was far superior in strength to stone and mortar, and it was easier to make than marble was to quarry and assemble.
Concrete: The Romans invented concrete, a strong and light building material. The Colosseum was built with thousands of tons of concrete, and it is still a popular monument today, enduring milleniums. Concrete is seen as a revolution to comtempary architecture because it is used worldwide today.
Whether you are responsible for a major thoroughfare, commercial parking lot or residential driveway featuring asphalt pavement, you have probably heard that timely crack repairs can extend the life of your pavement. Cracks that are left open to the elements allow water to penetrate to the pavement's supporting foundation. The foundation becomes unstable and incapable of bearing the weight of the pavement, frequently leading to widespread damage that can only be remedied by replacing the pavement. However, you may not know whether to choose a hot-pour or cold-pour sealant when you ask a contractor to repair the cracks in your pavement. An overview of the differences between the two types of sealants can help you make the best choice for your
The Pantheon was a Roman concrete structure. Roman concrete is a mixture of lime and volcanic ash (pozzolana, found near modern-day town Pozzouli). Roman concrete is also called hydraulic cement-based concrete. It is known for curing relatively rapidly, even in damp condition, thus it could be used for massive construction. The most daring thing about the use of Roman concrete in the Pantheon is that Portland cement needs steel reinforcement due to tendency of cracking caused by tension forces, meanwhile the Pantheon did not. The Pantheon still stands today is because of its special structure.
In this paper report we have discussed about the use of recycled concrete aggregate in the concrete and the effects on its compressive strength by progressively replacing the natural concrete aggregate (NCA) by recycled aggregate. It is the experimental study of recycled concrete aggregate (RCA) when it is compared with the natural concrete aggregate on account of its properties.
ement occupies approximately 50% of the mixed concrete volume and is responsible for physiomechanical properties of concrete. Cement production is essential to infrastructure and building construction, creating demands in very large quantities. Energy resources invested in the production process and resulting greenhouse gas emissions have become problematic. The cement production process has become among the world’s largest anthropogenic sources of carbon dioxide emissions, contributing to approximately 5% of global anthropogenic CO2 emissions, (WBCSD, 2009). Increased pressure is being placed on the industry to reduce CO2 emissions, owning to awareness regarding sustainability....
Concrete and Arch Arch is a curved structure usually supported by columns at each end. Arches were initially made of stones, bricks, and clay until the Roman strengthened the construction
In figure (2.26), eight equations proposed by different researchers have been plotted for lightweight concrete, as shown in table (2.12). The experimental splitting tensile strength values are calculated as follows: Eq. (2.23), (2.24), (2.25) (2.26) for cube specimens and (2.27), (2.28), (2.29), (2.30) for cylinder specimens. The splitting tensile strength of lightweight concrete for Eq. (2.23) ranged from 2.8 – 3.5 MPa, as shown in figure (2.23).
The role of fibers in concrete is to bridge across the cracks that develop some post cracking ductility and to increase it toughness and types of loading. The uses of reinforced concrete help to increase the strength and ductility but it req...
In this report, we will introduce and illustrate on precast concrete, pre-stressed concrete, ready-mix concrete, reinforced concrete, terrazzo and Urbanite in details.
Opus caementicium or Roman concrete is a synthetic construction substance that’s composed of an aggregate, a binding agent, and water. In Rome’s case, as discovered by UC Berkley with the extensive analysis of a sample of Roman concrete taken from a breakwater in Italy’s Pozzuoli Bay it was developed by using lime and volcanic rock which formed a mortar, the mortar and volcanic rock were then packed into wooden forms and when seawater was added a chemical reaction occurred, bonding everything together to create concrete (History, 2013). It is uncertain when Roman concrete was developed, but it was clearly in widespread and customary use from about 150 BC; some scholars believe it was developed a century before that.

Concrete is an extraordinary and key structural material in the human history. As written by Brunauer and Copeland (1964), “Man consumes no material except water in such tremendous quantities”. It is no doubt that with the development of human civilization, concrete will continue to be a dominant construction material in the future. However, the development of modern concrete industry also introduces many environmental problems such as pollution, waste dumping, emission of dangerous gases, depletion of naturalresources etc.
