Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
82 words
A fluid pouring repair material for mortar or the like wall which consists of a synthetic resin emulsion, hydraulic cement and aggregate slags with particle size less than 0.5 mm, and water as required to satisfy the following weight ratios wherein the weight ratios P/C, C/S and W/C are within the range of 0.1 to 0.3, 1.5 to 2.5 and 0.35 to 0.40, respectively, wherein P designates the solid content of the synthetic resin emulsion, C cement, S slags and W water.
Claim 2
Dependent Claim
82 words
A fluid pouring repair material for mortar or the like wall which consists of a synthetic resin emulsion, hydraulic cement and aggregate slags with particle size less than 0.5 mm, and water as required to satisfy the following weight ratios wherein the weight ratios P/C, C/S and W/C are within the range of 0.1 to 0.3, 1.5 to 2.5 and 0.35 to 0.40, respectively, wherein P designates the solid content of the synthetic resin emulsion, C cement, S slags and W water.
Claim 3
Dependent Claim
24 words
A pouring repair material for mortar or the like wall as claimed in claim 1 wherein the P/C ratio is from 0.1 to 0.2.
Claim 4
Dependent Claim
24 words
A pouring repair material for mortar or the like wall as claimed in claim 1 wherein the W/C ratio is from 0.360 to 0.390.
Claim 5
Dependent Claim
41 words
A fluid pouring material for mortar or the like wall according to claim 1 said synthetic resin emulsion contains an added filler in an amount within the range of 1.0 to 3.0 wt. percent of the solid contents of synthetic resin.
Claim 6
Dependent Claim
41 words
A composition according to claim 4 wherein said filler is selected from the group consisting of silica having a particle size range of from about 10 to about 40 μm and asbestos having a particle size of about 0.025 μmφ×5 μm.
Claim 7
Dependent Claim
34 words
A composition according to claim 1 wherein said synthetic resin is selected from the group consisting of an ethylene-vinyl acetate copolymer, a styrene-butadiene copolymer, and a styrene-butadiene copolymer partially modified with methacrylic acid ester.
Claim 8
Dependent Claim
13 words
A composition according to claim 1 wherein said hydraulic cement is Portland cement.
Claim 9
Dependent Claim
15 words
A composition according to claim 1 wherein said hydraulic cement is blast furnace slag cement.
Claim 10
Independent Claim
134 words
A method for repairing a blister in a composite wall comprising a concrete base wall and a decorative mortar wall coating wherein said blister is formed by separation of the decorative wall coating from the base wall leaving a space therebetween which comprises injecting through an opening in said decorative wall into the space formed by the blister a fluid composition consisting a hydraulic cement, water, synthetic resin emulsion, and aggregate slag having a particle size less than about 0.5 mm in the ratios P/C, C/S and W/C within the range of 0.1 to 0.3, 1.5 to 2.5 and 0.35 to 0.40, respectively, wherein P designates the solid content of the synthetic resin emulsion, C cement, S slags, and W water, thereby forming an adhesive bond between said base wall and said wall coating.
