What is the ratio for cement mix?
In terms of the ratio for concrete, it depends on what strength you are trying to achieve, but as a general guide a standard concrete mix would be 1 part cement to 2 parts sand to 4 parts aggregates. For foundations, a mix of 1 part cement to 3 parts sand to 6 parts aggregates can be used.
Is ready mixed cement any good?
Ready mixed concrete is guaranteed to provide a smooth finish, and a reliable drying time, and can be purchased in large bags, ready for water to be added.
What is the strongest concrete mix ratio?
A strong concrete mix would be something like 1:3:5 (Cement, Sand, Coarse Gravel). In this case, both the sand and gravel are the aggregate.
How many 20kg bags of cement makes a cubic Metre of concrete?
108 x 20kg bags
one 20kg bag will cover an area of 1.1m2 to a depth of approximately 10mm. or 108 x 20kg bags equates to one cubic metre of mixed concrete.
What happens if you put too much cement in concrete?
Since major force transfer in a concrete/mortar matrix is from sand-sand interaction, excess cement will turn the mortar very brittle since cement particles cannot transfer normal contact force – they are good at providing shear strength.
What area does a 20kg bag of concrete cover?
1.1m2
How long does ready mixed cement last?
Under normal conditions, concrete has a useable life of about 11⁄2 hours. However in summer it will lose workability more rapidly. Ideally, it should be placed and completely finished within 1 hour of discharge from the truck-mixer.
Is it cheaper to mix your own concrete?
One of the least expensive ways to get concrete is to mix your own. Otherwise, you risk getting a weaker concrete once it cures, which could lead to cracks or crumbles within a couple of years.
