Title: Innovations of Ara A Jeknavorian: Pioneering Advances in Concrete Technology

Introduction

Ara A Jeknavorian, an accomplished inventor based in Chelmsford, MA, holds an impressive portfolio of 20 patents. His contributions to the field of concrete technology have significantly advanced how concrete is monitored and utilized, particularly in construction applications. His innovations offer solutions that have the potential to enhance efficiency and effectiveness in mixing and working with concrete.

Latest Patents

Among his latest patents is the "Composition and method for obtaining exposed aggregates in surfaces of moulded concrete and other cementitious materials." This innovative surface retarder coating composition leverages both non-Ordinary Portland Cement (non-OPC) binders and OPC set retarder agents, supplied in a convenient powder form. On-site mixing with water allows for easy application onto mould surfaces via roller or spray equipment, enabling concrete casting within 30-60 minutes. The system is designed to retard the concrete setting, allowing for de-moulding the next day. This novel approach facilitates the revelation of the aggregate once the surface is removed using high-pressure water spray.

Another significant patent by Jeknavorian is the "Method for monitoring thixotropy in concrete mixing drum." This invention introduces an innovative way to measure thixotropy, defined as the reversible reduction in viscosity during mixing. Utilizing conventional slump monitoring equipment found in ready-mix trucks, this method involves monitoring energy required to rotate the mixing drum. By recording maximum and minimum energy values and comparing them with predetermined targets, the rheological factors can be adjusted by adding liquid components, ensuring consistency during transportation.
