Title: **Joseph P. Fleming: Innovator in Cementitious Compositions**

Introduction

Joseph P. Fleming, an accomplished inventor based in East Brunswick, NJ, has made significant contributions to the field of construction materials through his innovative work on cementitious compositions. With a portfolio of five patents, his inventions focus on enhancing the properties of cement through the development of advanced superplasticizers and additives.

Latest Patents

Fleming's most recent patents include his work on **Superplasticizers for Cementitious Compositions**. These superplasticizers are created from a mixture of naphthalenesulfonic acid formaldehyde condensate and free sulfuric acid, utilizing either a one-step or a two-step process. In the one-step process, the mixture is neutralized with a zinc compound, such as zinc oxide, achieving a pH of about 2, which results in a superplasticizer mixture that includes the free acid of the condensate and zinc sulfate. The two-step process involves an initial neutralization followed by further adjustment of pH to create a sodium salt mixture of the condensate.

Moreover, Fleming has developed **Additives for Cementitious Compositions**. These additives are combinations of sodium salts from the condensation product of naphthalenesulfonic acid and formaldehyde, along with various zinc salts. These mixtures significantly enhance the compressive strengths of cement while reducing water content, improving the overall performance of cementitious formulations.
