Can you use silica sand as a dry screed over underfloor heating pipes?
Unfortunately not. You require a 0-4mm sharp sand which can be purchased through most builders merchants. The mix should be approximately 1:4 Cement / Sand ratio. Mix to an earthy consistency and compact well. The cement is the conductor of the heat. Good luck with the project.

What is pack set problem for cement and how can you avoid it?
The pack set problem in cement refers to the phenomenon where cement particles agglomerate or clump together during storage, leading to reduced flowability and difficulty in handling. This can occur due to moisture absorption or prolonged storage. To avoid pack set, it is essential to store cement in a dry environment, use moisture-proof packaging, and minimize the storage duration. Additionally, regular monitoring of the storage conditions can help maintain the quality of the cement.
How do you determine the ratio of water to cement?
Concrete hardens as a result of the chemical reaction between cement and water so that for every 4 lbs of cement 1 lb of water is needed. The ratio is therefore 1:4 or 20%. This mix will be too dry so more water is needed than is technically necessary, the ratio should therefore be 35% to 40% and using a plasticizer

How can I make large cement planters?
To make large cement planters, you will need cement, sand, water, a mold, and a mixing container. First, mix the cement and sand in a 1:3 ratio with water to create a thick paste. Then, pour the mixture into the mold and let it dry for at least 24 hours. Once dry, remove the planter from the mold and let it cure for a few days before planting.

What weighs more wet sand or dry concrete?
Dry concrete weighs more than wet sand because concrete is denser and more compact than sand, even when wet. Concrete is composed of cement, sand, gravel, and water, which results in a heavier material compared to sand alone.
Why is your mortar turning into sand?
If it looks sandy when dry you haven t added enough cement; the mixture will be weak.

What is the cement to plaster ratio for a brick wall surfaces?
Hi there, I would use a 5-1 ratio of sand to cement and use a good mortar plastisier. Use plastering sand and mix well. Throughly soak the wall first and apply a light coat (scratch coat) Leave this to dry for a while and before it has completely dried, get the final coat on. Too much water on the wall will result poor bond between the Brick masonry and the plaster on account of lack of suction which is the primary mechanism by virtue of which the Cement Plaster will remain in position against the gravitational force.

How do you prepare concrete?
To prepare concrete, start by mixing the appropriate ratios of cement, sand, gravel, and water. A common mix ratio is 1 part cement, 2 parts sand, and 3 parts gravel, with enough water to achieve a workable consistency. Combine the dry materials thoroughly before gradually adding water and mixing until smooth. Ensure the mixture is uniform and free of clumps before pouring it into molds or forms.
