Also, What is a 1 2 3 mix for concrete?
Concrete is made from cement, sand, gravel and water. In making concrete strong, these ingredients should usually be mixed in a ratio of 1:2:3:0.5 to achieve maximum strength. That is 1 part cement, 2 parts sand, 3 parts gravel, and 0.5 part water.
Can I use just Portland cement by itself?

How do you make Portland cement?
Manufacturing. Portland cement clinker is made by heating, in a cement kiln, a mixture of raw materials to a calcining temperature of above 600 °C (1,112 °F) and then a fusion temperature, which is about 1,450 °C (2,640 °F) for modern cements, to sinter the materials into clinker.
What can I use instead of Portland cement?
– Pulverised Fuel Ash (PFA), aka ‘Fly ash’ as a cement substitute. PFA is a by-product of coal-burning power stations. …
