INFLUENCE OF ADMIXTURES ON THE RESISTANCE OF YOUNG CONCRETE TO CRACKING DURING RAPID DRYING OUT

EINFLUSS VON ZUSATZMITTELN AUF DIE WIDERSTANDSFAEHIGKEIT VON JUNGEM BETON GEGEN RISSBILDUNG BEI SCHARFEM AUSTROCKNEN

THE AIM IS TO CLARIFY THE EFFECT OF CONCRETE ADMIXTURES ON CRACKING IN YOUNG CONCRETE, AND TO INCREASE THE RESISTANCE TO CRACKING OF CONCRETE MADE WITH ADMIXTURES. THIN STRESSED CONCRETE SLABS ARE BEING SUBJECTED TO UNFAVOURABLE ENVIRONMENTAL INFLUENCES IN THE FIRST 24 HOURS AFTER MANUFACTURE; THEIR RESISTANCE TO CRACKING IS BEING OBSERVED.
