Can fiberglass be used to hold concrete together?
Yes, fiberglass can be used as reinforcement in concrete to improve its strength and durability. Fiberglass strands or mesh are typically added to the concrete mix to provide tensile strength and prevent cracking. This helps to hold the concrete together and enhance its structural integrity.
What is cement mad of?
Cement is hydrated limestone. Concrete is cement, stone and sand. Sometimes fiberglass fibers are added to increase strength.
What is supplementary cementitious material in concrete?
Supplementary cementitious materials are the mineral admixtures consisting of powdered or pulverized materials which are added to concrete before or during mixing to improve or change some of the plastic or hardened properties of Portland cement concrete.
What is the purpose of adding a curing compound to the concrete?
Curing is necessary for freshly cast concrete in order to maintain the moisture as the chemical constituents in cement react with water and heat evolves continuously until the setting process completes. The heat evolved during the setting of concrete is called heat of hydration, and this heat causes the water to evaporate. Proper and complete setting process is the most important phenomenon that imparts the desired strength to the concrete. If the freshly cast concrete is not cured, it develops cracks and also the chemical reactions will cease resulting in bad concrete.
Why steel is used to reinforce concrete explain it?
There are two main loading conditions that concrete under goes. These are Compression and Tension. Concrete is very strong in compression and is very weak in Tension (pulling apart). Concrete has so little strength to resist tension it is assumed to have no strength in tension. When civil engineers design concrete structures they can determine where the tension and compression will be located. Steel is added to give the concrete tensile strength. For Example a concrete beam when loaded from the top will experience compression on top section of the beam. The top portion of the beam will push inwards creating compression while the bottom section will pull apart creating tension. (Imagine a smile shape). :) Therefore reinforcement will be needed in the tension area (bottom).
Why 2 of gypsum is added to cement?
Gypsum is added to cement to decrease the setting time.
Why gypsum added to cement?
3% of gypsum is added to cement to "prevent the rapid setting of cement"
Why is gypsum added to Portland cement?
Gypsum is added to portland cement to retard C3A hydration
Is hydrated lime concrete?
No it is not. Hydrated lime and concrete are quite different. hydrated lime is an addative similar to cement and used in concrete to improve the strength. it can also be added to soil to improve stability etc. typically concrete is a mixture containing different % of rock, cement/lime, fly ash, water. lime is a cheaper then cement however not aas effective and takes longer to harden. -civil engineering student
Why 2 percent gypsum is added to the cement?
Because the gypsum only needs 2 percent added to the mix
Can fiberglass be used to hold concrete together?
Yes, fiberglass can be used as reinforcement in concrete to improve its strength and durability. Fiberglass strands or mesh are typically added to the concrete mix to provide tensile strength and prevent cracking. This helps to hold the concrete together and enhance its structural integrity.
What can be added to strengthen i.s.s.bricks?
To strengthen ISS bricks, additional reinforcing materials such as fibers or polymer additives can be added to the concrete mix. Increasing the density or adding more cement can also improve the strength of the bricks. Additionally, proper curing techniques and quality control during the production process can help enhance the overall strength and durability of the bricks.
Why 2 gypsum is added in the cement?
The construction industry uses both the natural and the synthetic forms of gypsum in Portland cement manufacturing. Although the amount of gypsum used in the mix represents a small percentage of the volume of all ingredients, gypsum has important functions.
What characteristic is common to all reinforced concrete bridges?
A common characteristic of reinforced concrete bridges is that they feature a combination of concrete and steel reinforcement to provide added strength and durability. The steel reinforcement helps to enhance the tensile strength of the concrete, allowing the bridge to better withstand forces like tension and bending.
How many ways to have improve concrete performance?
Prevent Premature Moisture Loss During Placing. Keeping the concrete moist and at an adequate temperature helps to provide proper hydration of the cement for maximum strength, increased density, lower permeability, and greater resistance to scaling. Pay special attention to placing and finishing.
What is concrete in architecture?
Concrete is the name commonly given to a mixture between a cementitious material and an aggregate with water added to chemically bond the materials during a curing process.Commonly used materials are portland cement and granite pebbles, with sand and other additives added to improve the concrete quality.The Roman Empire pioneered the use of concrete as a building material, as well as the use of arches to deal with large spans between columns. Concrete deals very well with compressive forces (pushing), but it will not work well against tension and torsion (pulling and turning). To improve this tensile strength; steel bars or cables are usually embedded into the concrete where tension or torsion is likely to occur.For a more complete explanation about concrete, you may try this link:http://en.wikipedia.org/wiki/ConcreteGood luck!
