METHOD AND APPARATUS FOR MEASURING QUANTITY OF ADMIXTURE IN READY-MIXED CONCRETE

摘要

A method of measuring the quantity of an admixture in ready-mixed concrete comprises the steps of collecting volatile components generated from the admixture, measuring the concentration of the collected volatile components, and deriving the quantity of the admixture in the ready-mixed concrete from the measured concentration of the volatile components. An apparatus for executing this method comprises a detecting probe and a main measuring unit. The probe includes a gas collecting section and a gas sensor. The main measuring unit for carrying out arithmetic operations on detected information received from the detecting probe, includes a microprocessor for controlling the operation of the entire apparatus, and a display for displaying the detected information received from the microprocessor.
