INFLUENCE OF THE STRUCTURE OF HYDRATED CEMENT PASTE ON THE BEHAVIOUR OF CONCRETE

INFLUENCIA DE LA ESTRUCTURA DE LA PASTA HINDRATADA DEL CEMENTO EN EL COMPORTAMIENTO DEL HARMIGON 711N IRREVERSIBLE CREEP, EXPANSION AND CONTRACTION. /TRRL/

An attempt is made to explain the influence of the micro-structure of hydrated cement paste on the behaviour of concrete. With the aid of the electron microscope it is possible to observe the morphology and the microstructure of the anhydride and hydrate components. The formation of the physical structure of the hydrated paste may be interpreted as an interwoven growth of colloid, in the form of needles which juxtapose forming plates, which in their turn, evolve into spirals. The porous system is composed of capillary pores and of the colloid pores. The different function of the water existing in the two types of pore determines the different behaviour of the hardened paste when subjected to phenomena such as drying shrinkage, reversible and irreversible creep, expansion and contraction.
