The Dry Cast Process | Pickford Precast Concrete

The Dry Cast Process | Pickford Precast Concrete

the “dry cast” method is a through coloured process, using specially selected sands and aggregates mixed with cement, water proofer and pigment where necessary to achieve the desired colour and finish. dry cast units are immediately demoulded after casting and are hand finished to a very high standard.

Density of Concrete - Testing Unit Weight of Concrete

Density Of Concrete - Testing Unit Weight Of Concrete

the density (unit weight) of concrete is measured using a type b pressure meter (see photo) to verify agreement with the approved project mix design.the information obtained through this test can also be used to determine yield and relative yield, which helps you verify that you are getting the volume of concrete you ordered and paid for.

Performance Specifications for Buildable Internal

Performance Specifications For Buildable Internal

a. installation with freshly cast concrete panels should be avoided. this is because hydration of cement and evaporation of water create the stress within the young concrete, causing shrinkage. b. provide gaps between the walls and structures: 20 mm for top, 20 mm for bottom and 10 mm for each side.
