What are the components of reinforced cement concrete?
steel,cement, sand
What is setting of Portland cement?
In normal usage, allowing the concrete to "set" is the same same as allowing the concrete to "cure". This process starts soon after you mix the cement and aggregate with water, and is a result of the water in the mix chemically binding with cement components. As the concrete sets or cures, the mixture gets harder. Depending on the proportions of the materials in the concrete, after a few hours the concrete will be hard enough to support the weight of the workers as they perform finishing operations (trowelling). After a couple of days, the concrete will typically be hard enough to remove formwork, as long as no loads are imparted to the concrete in doing so. Concrete in the US is typically specified as the compressive strength reached after 28 days. The term "initial set" is used informally to represent the time, after about 4 or 5 hours, where the concrete materials are beginning to bond chemically, and at which point the concrete must be undisturbed or irreparable damage to the structure will occur. All consolidation, compaction and initial floating (levelling) needs to be complete well before the concrete begins its initial set.
What type of concrete should you use when making a concrete bench?

What are the components of reinforced cement concrete?
steel,cement, sand
Is concrete a homogeneous or heterogeneous?
It is the former.
What are the 6 common structural components?
Wood, masonry, concrete, metal, glass, plastic.
Why although concrete components are elastic concrete is inelastic?
Well this is not quite true. Aggregate is a key component of concrete and is inelastic. In addition concrete pillars and beams will bend slightly under load and is thus not 100% inelastic. Polymer modified concrete and rebar modified concrete is also slightly elastic.
What is reinforced concrete?
Reinforced concrete is concrete reinforced with steel bars because although concrete is very strong in compression (depending on its components) it is very weak in tension and the steel bars make up for the required tensile strength.
Is the internet a concrete noun or an abstract noun?
Yes, the noun 'internet' is a concrete noun; a word for the communications system that connects computers and computer networks all over the world; a word for a physical system.
What are the components of concrete?
cement fine aggregates and course aggregates and water for the hydration of cement are the main component of plain cement concrete. and for RCC M-S bars are used with these component.
What are homogeneous and heterogeneous substances?
Homogeneous materials have undistinguishable components: salt water, wine, rubbing alcohol.Heterogeneous materials have distinguishable components and more phases: concrete, bricks, foods, wastes etc.
What was the total weight of concrete for tower bridge?
There was virtually no wire used in the construction of Tower Bridge. Its main components are 70,000 tons of concrete, 11,000 tons of steel and it is clad in Cornish granite and Portland stone.
What are the examples of concrete devices in computing?
