METHOD ANALYSIS OF WATER AND CEMENT RATIO IN CEMENT GROUT

摘要

FIELD: construction industry. SUBSTANCE: first conduction of cement grout is measured, then maximum value of conduction is found. Finally time up to moment of start offsetting is determined. Conduction coefficient is calculated by formula. Value of water- cement ratio in cement grout is judged by dependence of conduction coefficient on water-cement ratio established in advance. EFFECT: enhanced authenticity and accuracy of method. 2 dwg
