Diffeece between nominal mix and design mix?
a nominal mix is that mix in which we adopt the various ingredients such as1:2:3,1:2.5:4etc here the strength will not be the desired strength and generally here we take the ingredients per unit vol a design mix is that mix in we find the ratio of the different ingredients as per the desired strength and the ingredients would be in per unit weight

What is the concrete mix for concrete?
Normally it's a one-two-three mix. One part cement, 2 parts sand, 3 parts aggregate. The sand is graded which means it has a variety of grain sizes.

How many tons of screed to 1 cubic meter?
The weight of screed can vary depending on its composition, but on average, 1 cubic meter of screed weighs approximately 1.8 to 2.2 tons. This typically includes traditional sand and cement screed. For more precise calculations, it's best to check the specific density of the screed mix being used.

What are the best practices for preparing a surface for tiling using screed sand?
To prepare a surface for tiling using screed sand, follow these best practices: Clean the surface thoroughly to remove any dirt, debris, or grease. Ensure the surface is level and smooth by using a screed sand mix to fill in any uneven areas. Use a primer or bonding agent to help the screed sand adhere to the surface. Allow the screed sand to dry completely before tiling to ensure a strong bond.
What is the function of the floor screed?
The function of floor screed is to make a structural level floor surface above a waterproof membrane. It is usually made by either pumping in a special mix of self- levelling runny 'concrete - like' material or more traditionally a sharp sand and cement mix. Traditional screed is tamped by a large flat wooden or aluminum beam, which is called a screed, from which screed gets it's name. It should be very flat once finished and can be tiled once it has dried out, which can take weeks. It is usually laid over an insulation foam and often has electric heating elements or warm water pipes in it to make it into a large radiator. Thin screed needs to be reinforced to make it strong enough for the loads that are put on top of it which can be steel mesh or special fibres. This means that thinner screeds are often made up of specialist ingredients to make them self levelling and strong.

What is class 30 design mix?
M30 mix should be a mix design in laboratory with the available raw materials that is used in the preparation of concrete. The aggregates, sand have different compressive strength, water absorption and these values are used in mix design.

What is rich mix concrete design compare to normal mix?
it has more cement than the normal mix
Floor Screed mix ratio?
The acceptable standard is 4:1 (That is 4 wheelbarrows of sand to TWO bags cement) as the volume of a wheelbarrow is roughly double that of a 50kg bag of cement. Lots of builders get "confused" by this.
