Abstract
Abstract The invention relates to a filiform addition for concrete or mortar consisting of a filament or a filament bundle. The filament or filament bundle carries at least one body having a diameter larger than the thickness of the filament or filament bundle. At the same time, the length of the filament or filament bundle is greater than the diameter of the body.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
75 words
In a granular concrete and mortar composition, the improvement comprising using a granular concrete and mortar aggregate which consists of a body traversed by at least one filament whose length is greater than that of the body and whose diameter is smaller than that of the body so that portions of the filament whose lengths are greater than that of the portion of the filament within the body project from opposite sides of the body.
Claim 2
Dependent Claim
75 words
In a granular concrete and mortar composition, the improvement comprising using a granular concrete and mortar aggregate which consists of a body traversed by at least one filament whose length is greater than that of the body and whose diameter is smaller than that of the body so that portions of the filament whose lengths are greater than that of the portion of the filament within the body project from opposite sides of the body.
Claim 3
Dependent Claim
27 words
The aggregate defined in claim 1 wherein a bundle of such filaments all traverse said body and have portions extending codirectionally on opposite sides of said body.
Claim 4
Dependent Claim
38 words
The aggregate defined in claim 1 wherein said filament extends into another such body spaced from the first mentioned body by a distance greater than the length of the portion of said filament within the first mentioned body.
Claim 5
Dependent Claim
47 words
The aggregate defined in claim 1 further comprising at least one other filament traversing said body in a direction perpendicular to the first mentioned filament and having portions extending from opposite sides of said body of lengths greater than the length of said filament within said body.
Claim 6
Dependent Claim
49 words
The aggregate defined in claim 4 further comprising other filaments traversing each of said bodies in a direction perpendicular to the first mentioned filament and having portions extending from opposite sides of each of said granules of lengths greater than the lengths of said other filaments within said granules.
Claim 7
Dependent Claim
18 words
The aggregate defined in claim 5 further comprising additional such bodies traversed by each of said other filaments.
Claim 8
Dependent Claim
40 words
The aggregate defined in claim 1 wherein the diameter of said body is 10 to 1000 times greater than the thickness of said filament and the diameter of said body is not greater than one-third the length of said filament.
Claim 9
Dependent Claim
27 words
The aggregate defined in claim 7 wherein said body is composed of a material selected from the group which consists of a mineral, synthetic resin and cellulose.
Claim 10
Dependent Claim
28 words
The aggregate defined in claim 7 wherein said body is composed of a material having a density less than that of other components of the concrete or mortar.
Claim 11
Dependent Claim
14 words
The aggregate defined in claim 7 wherein said body has at least one cavity.
Claim 12
Dependent Claim
16 words
The aggregate defined in claim 1 wherein said filament has ends bent respectively in hook shape.
Claim 13
Dependent Claim
12 words
The aggregate defined in claim 1 wherein said filament forms a ring.
Claim 14
Dependent Claim
35 words
A process for making the aggregate defined in claim 1 which comprises the steps of: applying drops of a thermoplastic synthetic resin to a heated filament and fusing said filament thereto; and cooling said drops.
Claim 15
Dependent Claim
12 words
The process defined in claim 13 wherein said synthetic resin is polystyrene.
Claim 16
Dependent Claim
30 words
A method of making the aggregate defined in claim 1 which comprises the steps of: embedding said filament in a body of a foamable material; and thereafter foaming said body.
Claim 17
Dependent Claim
40 words
A method of making the aggregate defined in claim 1 which comprises the steps of: applying bodies to a length of said filament at spaced apart locations; and thereafter cutting said filament between said bodies into sections carrying said bodies.
