CREEP OF STRUCTURAL LIGHTWEIGHT CONCRETE

KRIECHEN VON KONSTRUKTIONS-LEICHTBETON

A TEST PROGRAMME IS AT PRESENT BEING CARRIED OUT ON THE BENDING MEASUREMENT OF HIGH STRENGTH LIGHTWEIGHT CONCRETE. THIS PROGRAMME IS TO BE SUPPLEMENTED BY CREEP OBSERVATIONS ON 4 LIGHTWEIGHT CONCRETE TYPES WHEREBY MEASUREMENTS WILL BE CARRIED OUT ON THE FOLLOWING HIGH STRENGTH LIGHT CONCRETE TYPES TO DETERMINE THE CREEP: A: LIGHTWEIGHT CONCRETE TYPE 1: (LBN 550 WITH LIAPOR 8). 5 CREEP TESTS FOR STUDYING THE EFFECT OF LOADING TIME, MOISTURE CONDITIONS AND VARYING LOADS. B: CONCRETE TYPES 2 TO 4 (LBN 250 WITH LECA, LBN 450 AND LBN 250 WITH BERWILIT) EACH TEST WITH LOADING AGE OF 28 DAYS, TO DETERMINE A TYPICAL CREEP VALUE.
