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.

Méthode de mesure de la quantité d'un adjuvant dans le béton préparé comprenant les étapes suivantes : recueillir les composants volatils produits par l'adjuvant; mesurer la concentration des composants volatils recueillis, et calculer la quantité d'adjuvant présente dans le béton préparé à partir de la concentration mesurée des composants volatils. Un dispositif permettant d'appliquer cette méthode se compose d'une sonde de détection et d'une unité principale de mesure. La sonde comprend une partie collectrice de gaz et un capteur de gaz. L'unité principale de mesure servant à effectuer des opérations arithmétiques sur les données mesurées provenant de la sonde de détection comprend un microprocesseur pour contrôler le fonctionnement de tout le dispositif, et un écran pour afficher les données mesurées provenant du microprocesseur.
