What else can I help you with?
Can you dry pour concrete without adding water?
No, you cannot dry pour concrete without adding water. Water is necessary to activate the chemical reaction that causes the concrete to harden and set properly.
What are the causes of concrete floor cracks?
Underlying soils movemnent. Adding to much water to concrete mix and getting shrinkage cracks. Not curing the concrete with water and it dries to fast.
What is Most important component to determine the strength of a concrete mix?
The concrete mix should be a 5:1 Cement to water ratio. make sure you mix thoroughly when adding water. Look up "Concrete slump test"
Why water is added to the concrete mix?
Water is added to concrete mux because without it, the mix could not stay moist long enough for it to get spread and leveled. <><><> Adding water starts a chemical reaction when the concrete CURES (not dries) into a solid mass. No water, your mix sits there as a dusty mix of sand, aggregate, and Portland Cement. Too much water, and your finished concrete will be of low strength.
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.
Is wet concrete heavier then dry concrete?
Concrete is made of a mixture of cement, aggregate (small stones), fine aggregate (sand), water and other chemical additives. When mixed the wet concrete will remain so for Most people assume that set concrete has no water in it, this is not so, as the water content helps bond the aggregates and cement, this process is known as Hydration. Concrete with no water in it would crumble to dust. Adding more water to the mix will make a concrete that is easier to work, while less water will produce a stronger, more durable concrete. After initial setting of the concrete, a slow amount of water loss is expected due to the concrete drying, it can take anything up to a year for water to stop evaporating slowly out of the concrete. So for this reason the answer to your question is yes, dry, set concrete will weigh less than wet concrete, but for anything up to a year it will keep getting lighter, due to waterloss.
How to make concrete bonding agent?
To make a homemade concrete bonding agent, mix together equal parts of Portland cement and water to create a slurry. This slurry can be applied to the surface before adding new concrete to improve adhesion. Additionally, adding a bonding adhesive or acrylic fortifier to the mix can also improve bonding properties.
Is cement waterproof?
Cement itself is not waterproof, but when mixed with water and other materials to make concrete, it can be made waterproof by adding additives or sealants.
What are the effects of adding eggshell in the mixture of concrete?
texture
How can I make a concrete slab?
To make a concrete slab, you need to prepare the site by leveling the ground and adding a base layer of gravel. Then, create a form to contain the concrete mix. Mix the concrete with water according to the instructions, pour it into the form, and level it with a screed. Allow the concrete to cure for several days before removing the form.
Does 25 klilo bag of unmixed concrete weigh the same when mixed?
i wouldn't think so! this is a 55lb. bag of concrete. water weighs 8lbs. per gallon. so you would need to figure out how many gallons of water you are going to use. should be some type of guide line on bag. but remember some of that water will evaporate. so an exact weight would be hard to figure, until the concrete was cured and actually weighted.
What is the advantage of adding both fine and course aggregate to cement when making concrete?
they give a goodstrength for concrete
