Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
17 words
The concrete or mortar of claim 1 wherein all the aggregate in said concrete is fine aggregate.
Claim 2
Dependent Claim
11 words
The concrete or mortar of claim 1 containing a cure accelerator.
Claim 3
Dependent Claim
14 words
The concrete or mortar of claim 3 wherein said cure accelerator is calcium chloride.
Claim 4
Dependent Claim
135 words
Concrete having simultaneously greater strength per weight, low shrinkage, low porosity and a superior as-molded surface, comprising a cured compacted mixture of graded fine and coarse aggregates with hydrated cement in a preparation such that the amount of cement is approximately equal to and no greater than the amount of void space of the compacted fine aggregates, said cement being compacted to a density approaching a maximum for the dry state and being located almost entirely in the voids between said fine aggregate particles so that the fine aggregate particles bear substantially directly on other fine aggregate particles and the combined volume of said fine aggregate and cement being no less than the volume of the void space that would lie between the particles of said coarse aggregate were said coarse aggregate compacted by itself.
Claim 5
Dependent Claim
94 words
The concrete of claim 5 wherein one component of said aggregate is much lighter in weight than another component thereof and the lighter-weight component is small enough in particle size relative to the particle size of said other component so that the forces of apparent viscous drag in the fluid-like dry mixture of cement and aggregate from which said concrete is made exceed the apparent buoyancy forces In the dry mixture so that said dry mixture remains geometrically stable and is constrained when water is infused to convert said dry mixture to said concrete.
Claim 6
Dependent Claim
76 words
The concrete of claim 5 wherin one componet of said aggregate is much lighter in weight than another component thereof and the size and quantity of the lightweight component are such that as a consequence of proper compaction, it fits completely and for all time is constrained, within the void spaces of said other component, the quantity and proportion of said other component being such that the particles thereof touch each other in the completed mix.
Claim 7
Dependent Claim
109 words
A lightweight concrete having good strength, and good strength-weight ratio, comprising a mixture of cement and optimally graded aggregates, wherein one component of said aggregate is much lighter in weight and smaller in particle size than another component thereof, the lighter-weight component being small enough relative to the particle size of the other component so that the forces of apparent viscous drag in the fluid-like dry mixture of cement and aggregate from which said concrete is made exceed the apparent buoyancy forces in the dry mixture so that said dry mixture remains geometrically stable and is constrained when water is infused to convert said dry mixture to said concrete.
Claim 8
Dependent Claim
90 words
A lightweight concrete having good strength, and good strength-weight ratio, comprising a mixture of cement and optimally graded aggregates, wherein one component of said aggregate is much lighter in weight than another component thereof and the size and quantity of the lightweight component are such that as a consequence of proper compaction, it fits completely, and for all time is constrained, within the void spaces of said other component, the quantity and proportion of said other component being such that the particles thereof touch each other in the completed mix.
Claim 9
Dependent Claim
35 words
The lightweight concrete of claim 8 wherein said lighter-weight component consists of material chosen from the group consisting of foamed silica, foamed ceramic, foamed polystyrene, phenolic microballoons, sawdust, wood flour, cotton linters, and organic fibers.
Claim 10
Dependent Claim
46 words
The concrete or mortar of claim 1 wherein said cement contains filler consisting of particles in the order of less than one micron in diameter, said particles fitting within the voids between the particles of said cement, thereby reducing the porosity of the concrete or mortar.
