For concrete roofing, Grade 43 or Grade 53 cement is typically recommended due to their high strength and durability. Grade 53 cement, in particular, offers superior compressive strength, making it ideal for structures that require enhanced load-bearing capabilities. Additionally, using cement with low permeability can help improve the roofing's resistance to moisture and weathering. Overall, the choice between these grades may depend on specific structural requirements and local building codes.
M40 grade of concrete : is recommended in extreme exposure or when very heavy loads are to be carried (like pier of a bridge etc) Under extreme exposure - reinforced M40 grade concrete should have minimum cement = 360 kg/cubm. This can vary from 300 to 360 for exposures from mild to extreme. Plain M40 grade used under mild to extreme exposure has minimum cement content from 220 to 280 kg/cubm Other considerations like admixtures (fly ahs etc) and actual mix design is the best method of arriving at minimum cement contents.
The Concrete mixing ratio for M35 grade concrete as per IS Mix design is1:1.6:2.907 (cement:Fineaggregate:Coarse aggregate)The ratio obtained is as per design calculations by considering the grade of aggregates and the type of cement used.The Water/cement ration is 0.43
Roofing cement typically takes about 24 to 48 hours to dry completely, depending on factors such as temperature, humidity, and the thickness of the application. However, it may be ready for light foot traffic within a few hours. For optimal results, it's best to follow the manufacturer's instructions regarding drying times. Always ensure proper ventilation and conditions for drying.
I think that they can, if they are both used correctly, the cement and concrete bricks can be put together in the same wall construction. :) <><><> I think you need to define some words. Concrete is made by mixing portland cement, water, and sand/crushed stone. There ARE no "cement bricks" Traditional bricks are made by mixing clay, shale, and water, and baking them in a kiln (oven) at high temperatures. And yes, regular clay brick and concrete brick/ block are frequently both used in a wall. Together.
The best grade of concrete for a driveway typically ranges from 3,000 to 4,000 psi (pounds per square inch). This strength provides the necessary durability to withstand the weight of vehicles and resist cracking due to freeze-thaw cycles. For areas with heavy traffic or extreme weather conditions, a higher grade, such as 4,500 psi, may be recommended for added strength and longevity. Additionally, using a proper mix design with appropriate additives can enhance performance.
The best cement for house construction depends on the specific needs of your project. Ordinary Portland Cement (OPC) is ideal for general construction, with 53 Grade OPC being suitable for high-strength concrete. Portland Pozzolana Cement (PPC) offers chemical resistance and is perfect for large-volume RCC work and areas exposed to moisture. Portland Slag Cement (PSC) is excellent for mass concrete work and coastal areas due to its resistance to sulphates. For more details, read more here.
Concrete roofing tiles are extremely strong and capable of withstanding the most brutal weather conditions. They are even fireproof. The tiles consist of a cured product made of cement, sand and pigments.

For drilling into cement, a masonry drill bit is best suited due to its ability to effectively penetrate hard surfaces like concrete.
The best method for repairing cracks in concrete using cement filler is to clean the crack thoroughly, apply a bonding agent, fill the crack with a cement mixture, and smooth it out with a trowel. Allow the filler to cure according to the manufacturer's instructions for a durable and long-lasting repair.
Without aggregates or sand it is not concrete.
The best flooring option for a basement with a cement floor is vinyl plank flooring. It is durable, moisture-resistant, and easy to install over concrete surfaces.

You could add lime putty. But the best solution would be to get a cement that sets in the amount of time you need, a 'slow setting cement'.
The best techniques for creating a durable concrete structure using a sand mix include proper mixing of sand and cement, ensuring the correct water-to-cement ratio, thorough compaction of the mixture, and proper curing of the concrete. These steps help to enhance the strength and durability of the structure.
The number of bags of cement needed for a 3000 psi concrete mix can vary depending on the specific mix design, but a common ratio is approximately 1 bag of cement (94 lbs) for every 1 cubic yard of concrete. A typical mix for 3000 psi concrete might use a 1:2:3 ratio of cement, sand, and gravel. Therefore, for a cubic yard of 3000 psi concrete, you would typically use one bag of cement. However, for precise calculations, it's best to consult a concrete mix design guide or professional.
