The concrete is 6 in. thick and is mixed in the proportion of one part cement, two parts sand and three parts gravel. Enough water is added to make it of a quaky consistency so that when struck with a straight edge a small amount of water will appear on the surface.
A floor laid according to this method will not wear slippery.
To get the best results, freshly laid concrete should be protected from extremes of temperature. A wet straw covering during the hot weather prevents a too rapid hardening, but it should not be put on until the surface of the work has set somewhat.
n freezing weather, fresh concrete should be covered with straw just after it begins to set and this covering should be left on for at least thirty-six hours.
