Abstract
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.

Claim 2
Dependent Claim
36 words
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.
Claim 3
Dependent Claim
29 words
The composition of claim 1 wherein said aggregate is selected from the group consisting of sand, cement stack dust, fly ash, perlite and vermiculite and mixtures of one another.
Claim 4
Dependent Claim
26 words
The composition of claim 1 wherein said hydraulic cement is selected from the group consisting of portland and lime-containing portland cement and mixtures of one another.
Claim 5
Dependent Claim
20 words
The composition of claim 1 wherein said polyethylene strips have a longitudinal dimension about thirty-two times that of their width.
Claim 6
Dependent Claim
69 words
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.
Claim 7
Dependent Claim
69 words
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.
Claim 8
Dependent Claim
71 words
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.
Claim 9
Dependent Claim
71 words
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.
Claim 10
Dependent Claim
62 words
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).
Claim 11
Dependent Claim
62 words
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).
Claim 12
Dependent Claim
69 words
A process as in claim 7 wherein said admixing of said aggregate comprises: a. selecting said aggregate from the group consisting of sand, cement stack dust, fly ash, perlite and vermiculite, mixtures of said sand, stack dust, fly ash and perlite, and mixtures of said sand, stack dust, fly ash and vermiculite; and b. adding said aggregate sequentially in the following order: stack dust, sand, perlite, vermiculite, fly ash.
