Abstract
A study is conducted to determine the engineering properties viz. Compressive
strength by partial replacement of Portland cement in mortar by Al=Jufra limestone
(JLS). Mortar is the bonding agent that integrates brick into a masonry assembly.
Mortar must be strong, durable and capable of keeping the masonry intact, and it must
help to create a water-resistant barrier. These requirements are influenced by the
composition, proportions and properties of mortar ingredients. The partial
replacement of cement material with a limestone considered as (5, 10, 15, 20, 25, 30,
35 and 40%). The compressive strength of hardened cement mortar samples are found
at age 28 days. Results showed that the maximum compressive strength is obtained
only at 5% replacement. This result gives clear picture that (JLS) can be utilized in
cement mortar mixture as a good substitute for cement at 5% replacement.
