  • Abstract:

Production of cement consumed large amount of energy couple with release of harmful gases like CO into the 2
atmosphere. Every effort to successfully replace its usage in construction industry is a giant achievement. So many
confirmed properties of cement establish its usage as an essential construction material. Therefore any material that
will partially replace it must also be tested for the various properties that make cement desirable. Therefore, this
research has been able to evaluate the effects of bamboo leaf ash and Locust beans pod ash admixtures, and their
mixture proportions on autogenous shrinkage strain and compressive strength of mortar specimens. The auto
shrinkage strain was carried out using a cylindrical mortar specimen of 75 mm x 300 mm dimension and the volume
changes were measured for the various pozzolanic concrete mixes. The compressive strength test was also carried out
using 50 mm x 50 mm x 50 mm mortar specimen crushed with ELE international ADR 1500 compressive machine . The
various test were carried out at 7, 14, 21 and 28 day. The results of the compressive strength test show that both
bamboo leaf and locust beans pod ashes did not alter the compressive strength of their corresponding mortar
significantly. The auto shrinkage results also show that both pozzolans possesses the ability to improve the auto
shrinkage of these mortar mixes.
