## Abstract

A composition for producing an unsaturated polyester is provided. The composition comprises an unsaturated polyester resin; cement; sand; bleaching agent; and curing agent.

## Claims

### Claim 1

An unsaturated polyester composition consisting essentially of:
an unsaturated polyester resin;
cement;
sand;
a bleaching agent; and
a curing agent.

### Claim 2 (depends on 1)

The composition as defined in claim 1, wherein the weight ratio of said curing agent to a mixture of said unsaturated polyester resin, cement, sand and bleaching agent is from 300:1 to 500:1.

### Claim 3 (depends on 1)

The composition as defined in claim 1, wherein said bleaching agent is titanium dioxide (TiO.sub.2).

### Claim 4 (depends on 2)

The composition as defined in claim 2, wherein said curing agent is selected from the group consisting of methyl ethyl ketone peroxide (MEKPO), dimethyl phthalate (DMP) and cyclohexanone peroxide (CHPO).

### Claim 5

An unsaturated polyester composition consisting essentially of
an unsaturated polyester resin;
cement;
sand;
a bleaching agent, and
a curing agent
wherein the weight ratio of said curing agent to a mixture of said unsaturated polyester resin, cement, sand and bleaching agent is from 300:1 to 500:1;
said bleaching agent is titanium dioxide (TiO.sub.2); and
said curing agent is selected from the group consisting of methyl ethyl ketone peroxide (MEKPO), dimethyl phthalate (DMP) and cyclohexanone peroxide (CHPO).

### Claim 6

An unsaturated polyester composition consisting of:
an unsaturated polyester resin;
cement;
sand;
a bleaching agent; and
a curing agent.

### Claim 7 (depends on 6)

The composition as defined in claim 6, wherein a weight ratio of said curing agent to a mixture of said unsaturated polyester resin, cement, sand and bleaching agent is from 300:1 to 500:1.

### Claim 8 (depends on 6)

The composition as defined in claim 6, wherein said bleaching agent is titanium dioxide (TiO.sub.2).

### Claim 9 (depends on 6)

The composition as defined in claim 6, wherein said curing agent is selected from the group consisting of methyl ethyl ketone peroxide (MEKPO), dimethyl phthalate (DMP) and cyclohexanone peroxide (CHPO).

### Claim 10 (depends on 6)

The composition as defined in claim 6, wherein a weight ratio of said curing agent to a mixture of said unsaturated polyester resin, cement, sand and bleaching agent is from 300:1 to 500:1;
wherein said bleaching agent is titanium dioxide (TiO.sub.2); and
wherein said curing agent is selected from the group consisting of methyl ethyl ketone peroxide (MEKPO), dimethyl phthalate (DMP) and cyclohexanone peroxide (CHPO).
