Improvements in the Manufacture of Mortars, applicable also as Fire-
proof, Soundproof, or Nonconducting Compositions.

I, WILLIAM JAMES CHRYSTAL, of Shawfield, Rutherglen, in the County of
Lanark, Chemist, do hereby declare the nature of this invention to be as follows:-
This invention relates to the manufacture of mortars suitable for building
purposes, also for fire-proofing, deafening, rendering buildings vermin proof,
covering steam boilers and pipes, and for other purposes.
This improvement consists in mixing together certain waste or bye products
in the proper proportions whereby calcium hydrate, ferric oxide, calcium sul-
phate hydrate and silicious matter are brought together so as to combine into
a hard setting compound. I use one part of lime waste, consisting largely of
hydrate of lime and containing peroxide of iron, magnesia and alumina: one
part of vat or soap waste which, on oxidation by the atmosphere, contains a large
proportion of calcium sulphate hydrate, which is in a certain condition the main
constituent of plaster of Paris; and one part of sand, ashes or other silicious
matter. I grind these up together wet in a mortar mill or other approved
apparatus to a proper consistency, adding water if required. The proportions
may be varied according to circumstances but by experience I have found the
proportions given as suitable for building operations, fireproofing and deafening.
For boiler and pipe covering, whether for heat or cold, I add to the mixture
described any fibrous material, such as hemp waste, crude asbestos, cocoa nut
fibre, esparto grass, or paper work refuse, and also if it is desired to make it
more plastic or adhesive to the boiler or pipes any proportion of clay.

in and by the following statement:-

This improvement consists in mixing together certain waste or bye products
in the proper proportions whereby calcium hydrate, ferric oxide calcium sul-
phate hydrate and silicious matter are brought together so as to combine into
a hard setting compound.
1 use one part of lime waste, consisting largely of hydrate of lime and con-
taining peroxide of iron, magnesia and alumina: one part of vat or soap waste
which, on oxidation by the atmosphere, contains a large proportion of calcium
sulphate hydrate (which is in a certain condition the main constituent of plaster
of Paris); and one part of sand, ashes or other silicious matter. I grind these
up together, preferably wet, in a mortar mill, or other apparatus, to a proper
consistency, adding water if required. The proportions may be varied accord-
ing to circumstances but by experience I have found the proportions given as
suitable for building operations, fire-proofing and deafening.
For boiler and pipe covering, whether for heat or cold, I may add to the
mixture described any fibrous material such as hemp waste, crude asbestos,
cocoa nut fibre, esparto grass, or paper work refuse, and also, if it is desired to
make it more plastic or adhesive to the boiler or pipes, any proportion of clay.
If it is preferred, in order that the mixed materials may be packed in casks or
bags, the lime waste and the vat waste may be dried or roasted prior to grinding
or mixing. It will then be used in a similar manner as cement.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. A mortar or cement formed by mixing together as described, lime waste.
vat waste and silicious matter so as to form a hard setting compound suitable
for building purposes.
2. A hard setting compound suitable for fire-proofing, deafening, and render-
ing buildings vermin proof, formed by mixing together as described, lime waste,
vat waste and silicious matter.
3. A hard setting compound suitable for covering steam boilers and pipes and
for other purposes, formed by mixing together as described, lime waste. vat
waste and silicious matter.
