Abstract
A cementitious composition for the molding of relatively light-weight, heat-insulative, nailable, structural units such as bricks, blocks, roof decking, etc. The composition comprises an inorganic cementitious settable admixture within which is incorporated a significant proportion of a waste polyethylene consisting substantially of polyethylene derived from the reclamation of cellulosic fiber from fiberboard to which a polyethylene coating material was previously adhered. Additionally, the composition comprises a significant proportion of industrial waste commonly termed stack dust and/or fly ash as aggregate.
Claims8
A synthetic resin-inorganic cementitious settable composition, said composition consisting essentially of, by volume:
- a. about 1-4 parts polyethylene strips;
- b. about 2-8 parts aggregate;
- c. about 1-2 parts hydraulic cement;
- and
- d. about 1-4 parts water.
A synthetic resin-inorganic cementitious settable composition, said composition consisting essentially of, by volume:
- a. about 1.7 parts polyethylene strips;
- b. about 3.6 parts aggregate selected from the group consisting of sand, cement stack dust, fly ash and mixtures of one another;
- c. about 1 part hydraulic cement selected from the group consisting of portland and lime-containing portland cement and mixtures of each other;
- and
- d. about 1.7 parts water.
A structural unit molded from a synthetic resin-inorganic cementitious settable composition consisting essentially of, by volume, about 1-4 parts polyethylene strips;
- about 2-8 parts aggregate selected from the group consisting of sand, cement stack dust, fly ash, perlite and vermiculite and mixtures of one another;
- about 1-2 parts hydraulic cement selected from the group consisting of portland and lime-containing portland cement and mixtures of one another;
- and about 1-4 parts water.
A process for preparing a synthetic resin-inorganic cementitious settable composition, said process comprising the steps of:
- a. mixing about 1-4 parts, by volume, polyethylene strips and about 1-4 parts, by volume, water;
- b. admixing about 1-2 parts, by volume, hydraulic cement to the mixture of step (a);
- and
- c. admixing about 2-8 parts, by volume, aggregate to the mixture of step (b).
