| Abstract |
| Workability of cement, lime and sand mortars was studied
by the measurement of flow on a flow table. Effects of cement
and sand proportions were investigated by taking various
mixes from 1 : 1.0 to 1:5.0 cement : sand mortars. 1: 2.5,
1: 3.0 and 1:3.5 cement : sand mixes were further studied
by the use of lime as workability aid.
It was found that mixes of cement and sand from 1: 1.0 to
1:4.0 ratio behave like plastic masses and workability increases
by increase in water content without any yield
point. 1 :4.5 and 1:5.0 cement: sand mixes gave certain
yield values. Overall workability of various mixes with
different water content has shown that workability in·
creases from 1: 1.0 to 1 : 2.0 and thereafter it decreases
from 1: 2.5 to 1: 5.0 cement : sand mixes. The effect
of lime was that it increases the workability in each case
and the effect is more marked at higher lime contents in
the mixes. |
