Title: The Innovative Contributions of David G Dawson

Introduction

David G Dawson is a notable inventor based in High Wycombe, GB. He has made significant contributions to the field of cementitious compositions, holding a total of 3 patents. His work focuses on enhancing the properties of cement mixtures, which has important implications for construction and building materials.

Latest Patents

Dawson's latest patents include innovative methods for creating cementitious compositions with a modulus of rupture greater than 20 MN/m². This is achieved by subjecting a mixture of hydraulic cement, fine aggregate, a selected water-dispersible polymer, and water to a homogenization process. This process significantly reduces voidage in the final product, resulting in improved strength and moisture resistance. Another patent, U.S. Pat. No. 4,070,199, describes cured polymer-containing cementitious compositions that also exhibit high modulus of rupture. These compositions are created through a high shear mixing process, which includes the use of a water-dispersible acidic polymer that contains a specified proportion of carboxyl groups.
