Introduction

Ezrah Hanuka is a notable inventor based in Haifa, Israel. He has made significant contributions to the field of cement technology, particularly in the development of innovative cement mixes. With a total of two patents to his name, Hanuka's work focuses on enhancing the properties and performance of chemically bonded silico-phosphate cements.

Latest Patents

Hanuka's latest patents include advancements in cement mixes that contain additives for altering the hardening rate of chemically bonded silico-phosphate cements. One of his patents describes a cement mix for the preparation of a magnesium silico-phosphate cement (MSPC) with an altered hardening rate. This mix comprises approximately 1% of an [MF] salt or acid, which, upon the addition of water, produces a final set cement with similar physical properties to those of a mix lacking the additive, but with a significantly altered setting time. In preferred embodiments, retarders such as NaTiF and KTiF are utilized, while KAlF serves as an accelerant.

Another patent outlines a method for altering the hardening rate of MSPC by adding around 1% of an [MF] salt or acid. This addition can be made directly to the dry mix or to the water used for hydraulic hardening. The method significantly alters the hardening rate without negatively impacting the physical properties of the final set cement.
