Title: The Innovative Mind of Mohammed Shameem

Introduction

Mohammed Shameem, a prolific inventor based in Dhahran, Saudi Arabia, has made significant contributions to the field of cement chemistry and construction materials. With a portfolio of five patents, his work focuses on enhancing the performance and durability of concrete through innovative compositions.

Latest Patents

Among his latest patents, one notable invention is the "Cement composition containing an oil ash set retarder." This innovative composition utilizes oil ash comprising carbon in the range of 60% to 89% as an effective set retarder in cement mixtures. The incorporation of oil ash has shown to prolong the setting times of cement paste, retaining slump flow in concrete longer than compositions without the retarder. Additionally, the presence of oil ash marginally improves the compressive strength of concrete, offering a viable alternative to traditional commercial retarding admixtures, which often have limited shelf lives.

Another significant patent is titled "High performance concretes and methods of making thereof." This patent outlines a concrete composition that includes cement, fine aggregates such as sand, and coarse aggregates like crushed limestone. It also integrates industrial waste materials such as electric arc furnace dust, cement kiln dust, oil ash, and limestone powder. These high-performance concrete compositions, enhanced with industrial waste materials and nano silica, exhibit improved mechanical strength and durability, particularly in resistance to chloride ion penetration.
