The presence of moisture in sand will add considerable water to the mix. If the total water is not adjusted to compensate, the mix will have too much water.
Excessive water is the single most common cause of poor concrete. I makes a weaker mix and makes the concrete less resistant to freeze-thaw cycles. It will take a longer time before you can add floor coverings in the case of building slabs.

What is concrete . element compound mixture?
Concrete is a mixture containing cement, sand, gravel and water.
What is stronger concrete or Mortar?
Concrete is stronger than mortar.Because mortar is a mixture of cement, sand and water but concrete is a mixture of cement, sand, gravel and water. Thus concrete forms a stiff mix than mortar.Hence the concrete is more stronger than cement.
How is concrete made from cement?
Concrete is to bread as cement is to flour. Concrete is a mixture of sand, gravel, cement, and water.
Is concrete an homogeneous or heterogeneous mixture?
Concrete is considered a heterogeneous mixture because it is composed of various components such as aggregates (like gravel and sand) and cement that are visibly distinguishable.
Is concrete a pure substance or mixture?
Concrete is a mixture, not a pure substance. It is made up of various substances such as cement, water, aggregates (sand, gravel), and additives. Each of these components retains its own properties and can be physically separated from the others.
Is concrete a heterogenous mixture?
concrete is heterogeneous mixture. Ingredients in concrete are cement, sand, aggregates,and water. These are mixed based on mix design.
What is the volume of sand in 1 cubic meter of concrete?
Concrete is a mixture of cement, sand, stone, and water. In a cuibic meter of concrete, , there is about 0.3 cubic meters of sand, or about 475 kg
What is the ideal sand to cement ratio for achieving optimal strength in a concrete mixture?
The ideal sand to cement ratio for achieving optimal strength in a concrete mixture is typically 2:1. This means using two parts sand for every one part of cement. This ratio helps to ensure a strong and durable concrete mixture.
Is concrete matter?
yes Everything is matter at the molecular level. Concrete is a mixture of sand, gravel and water.
Does concrete weigh more than sand?
Yes, concrete typically weighs more than sand because it is a mixture of cement, water, and aggregates (such as sand and gravel). The density of concrete is greater than that of sand due to the combination of these materials.
What combines to make glass and concrete?
Common glass is made from sand, SiO2, Na2O and CaO. Concrete is a mixture of rocks (aggregate), sand, and water.
What is mixed with sand for building buildings?
Concrete is used for building buildings and it is a mixture of sand, water and cement.
