With a total of 7 patents, his work has garnered attention for its practical applications and environmental benefits.
Latest Patents
One of Maw-Tien Lee's latest patents involves producing cementitious materials with improved hydrophobicity and strength using reclaimed waste substances. This hydrophobic admixture is designed for cement paste, mortar, and concrete. It includes solid polymer particles coated with a hydrophobic agent and surfactant. These solid polymer particles adhere to the exterior surfaces of hydrated cement particles within the cement matrix. They effectively deliver the hydrophobic agent into the hydrophilic cement matrix, ensuring uniform distribution throughout. The solid polymer particles can be derived from crumb rubber particles from waste rubber tires, recycled plastics, and similar materials. The hydrophobic liquid agent is sourced from waste lubricant oil, spent motor oil, base oil, esters of fatty acids, and vegetable oil. Additionally, fine particles such as activated carbon, silica fume, and spent catalyst can be utilized to fill large pores or cracks in the cementitious matrix. The resulting cured materials exhibit high contact angles and impressive compressive strengths.
