The use of fiy ash in concrete blocks

Marina Álvarez Alonso、Olga Río Suárez1991-12-01Materiales de Construccion

This paper describes how fly ashes which are not prescribed by the standards can be used in the manufacturing of concrete blocks. To implement this proposal it was necessary to do tests of the constitutive materials of the blocks, and block tests. The objective of these tests is to obtain the optimum blocks. This pape…

Early age volume changes in concrete due to chemical shrinkage of cement paste

L. Ebensperger、R. Breitenbücher、R. Springenschmid1991-12-01Materiales de Construccion

Unrestrained early age volume changes due to chemical shrinkage in cement pastes, mortars and concretes have been determined. The measurements were performed on sealed and unsealed samples which were stored under water. The chemical shrinkage of unsealed specimens represents the amount of absorbed water due to the che…

Durabilidad del hormigón: Acción del agua de mar sobre un cemento portland resistente a los sulfatos. Influencia de la adición de escorias y de cenizas volantes

Demetrio Gaspar Tebar、José Luis Sagrera Moreno、Victoriano González Vila 等 4 位作者1991-12-01Materiales de Construccion

This article, is part of a long time ICCET investigation programs studies the variation of the mechanical resistance to flexotraction 1: 3 normalized mortar with 1 x 1 x6cm dimension, using sulphate-resistent portland cement mixed with 15-35-60 and 70% parts of a furnace slag, a fiy ash or silica sand. The samples wer…
