Definitions

  • This invention relates to an improved method of building construction.
  • the bricks, mortar and plaster finish have different chemical characteristics which often leads to cracking and structural failures due to the different coefficient of contraction when curing, particularly of the mortar and plaster.
  • the building block, mortar and plaster are all prepared from the same materials, the aggregate being graded in granular form for the block and pulverised for finer handling in the mortar and plaster.
  • a cementitious mixture having pozzolanic characteristics is used to manufacture the building blocks as disclosed in my patent specification no. 799545, the mixture comprising pulverised fuel ash (PFA) and Portland- cement with chalk as the aggregate.
  • PFA pulverised fuel ash
  • I provide a method of building construction comprising bonding together cured building blocks made from a cementitious mixture of pulverised fuel ash and Portland cement with chalk or limestone as the aggregate by a mortar including the same materials as that from which the blocks are made but in different proportions and then, if required, applying a finishing plaster to the blocks, the plaster including the same materials as that of the blocks and either the same or a different mix from that of the mortar.
  • the mix of the mortar and plaster being 2 to 6 parts by weight chalk or limestone, 2 to 6 parts by weight PFA and 1 part by weight cement.
  • the blocks are made of a mixture comprising 5 parts by weight chalk or limestone, 5 parts by weight PFA and 1 part by weight Portland cement.
  • the mix of chalk or limestone and PFA is chosen so that the strength of the cured mortar does not overcome that of the cured block and the strength of the cured plaster is such as to provide a permanent bond with the block and mortar.
  • t.he resultant structure is extremely strong due to its homogeneous nature, the bond between the block, mortar and plaster being such that on demolition it is almost impossible to separate the plaster from the blocks or the blocks from the mortar, unlike traditional structures using bricks and mortar where the bricks can often be salvaged due to their separation from the mortar.
  • This homogeneous bond is thought to be the result of a chemical reaction between the blocks, mortar and plaster, all having the same constituents but in different proportions.
  • the PFA is a material collected by precipitators from the flue gases of modern coal fired electric power stations. This is a waste material and is in the form of a very fine dust composed of the incombustible matter originally present in the coal.
  • the blocks are first allowed to mature and the mortar and, if required, the plaster applied in a green state.
  • Leaner or stronger mixes within the range stated above may be used to ensure that they do not overcome the strength of the block or vice-versa.
  • the pattern of drying shrinkage between the constituent materials can be reduced to a minimum and cracking can be eliminated.
