Material Scientist specialized in cement/concrete and associated materials used in the manufacture/production of these materials.

Manage and direct Mapei Cement Additive Division (CADD) technical support program for North America, and technical consultations for Mapei global customers.Established technical services program from scratch to support cement plants for clinker quality evaluation and optimize clinker reactive and cement hydration kinetic. Developed guidelines and procedures to optimize clinker and cement chemistry to achieve better burnability, better reactivity, better performance and better interaction in the concrete mixtures.

Direct technical staff; set objectives and activities, monitor and evaluate project progress and personal performance. Provide technical solutions including Portland Cement, Oilwell Cement, Concrete Mixtures, Supplementary Cementitious Materials, Aggregate. Provided internal trainings to the personnel at all levels of the organization, as well as to the external customers on the cement chemistry and mineralogy and concrete technology.Resolved several chronic product deficiency issues, improved product quality and boosted competitiveness of company’s products. Pioneered a sophisticated technical approach to investigate cement and admixtures / additives compatibility. The research helped the company optimize clinker and cement chemistry to have great flexibility in very diversified mixture systems without causing incompatibility problem in the field applications. Through the unique skills of observation, analytical, theoretical and problem-solving, helped the company solve many challenging technical issues arose from the fields, and avoided tens of thousand dollars claims, and increased the sales of the products.Played the key role and made significant contributions in several law suit cases in defending the company from large amount of monetary claims by providing detailed data analysis and conducting scientific investigations.Played the key role in recovering the back due from customers due to the quality dispute by analysing the claims, conducting investigations and experiments.

Managed diversified internal and external technical resources and contract research and development projects. Set guidelines for contract R&D projects. Developed a process control to produce highly stable cubic lithium cobalt oxide phases as rechargeable lithium ceramic cathotic materials, and significantly increased rechargeable cycles. The method was intellectually protected in the Patent. Awarded 1996 Technology Outstanding Performance.Established cement and concrete laboratory for supporting in–house cement and concrete research and testing.Formulated lithium–based chemical admixtures for applications to control alkali–silica reactions in the concrete.

Program and Project leader: ASR control chemical admixture product formulation; Set product manufacturing requirements, raw material and product specifications and quality control standards. Prepared project proposals and plans, wrote product support technical papers and project reports, and gave product promotion presentations.Formulated and developed chemical admixtures for cement and concrete (inorganic, organic and emulsion–based admixtures).Formulated and developed solidification system and chemical admixtures for contaminated soil remediation, solidification and stabilisation.
