The influence of fly ash addition on the autogenous shrinkage of high-strength concrete was respectively experimentally studied under the condition of that the compressive strength at 7 day and the w/b ratio were the same.

This paper introduces some types of concrete shrinkage, and also researchs how to expect the quantity of fly ash on the autogenous shrinkage and the drying shrinkage of the concrete.

Results shown that the addition of silica fume could increase the autogenous shrinkage a little and almost .

The multi-coefficient formula of free shrinkage strain for commercial concrete;

The general effect of Polynaphthalene Sulphonate Superplasticizer (PNS) on shrinkage cracking of mortars has been investigated by means of multi-channel ellipse ring shrinkage cracking test,free shrinkage and strength under drying conditions.

To reduce cracks due to concrete free shrinkage in canal engineering,polypropylene fibers,GGBFS and polycarboxylic acid-based superplasticizer were introduced into plain concrete.

The effects of the different content of special manufactured sand,fly-ash,waterproof admixture on the self-shrinkage of the cement matrix grouting paste were studied in this article.

The drying shrinkage and self-shrinkage of concretes with different water to binder ratios were studied.

Dynamic models of hydration reaction of Portland cement and autogenous shrinkage of concrete;

The influence of W/B ratio and fly ash addition on the autogenous shrinkage of concrete with same strength;

Early autogenous shrinkage and dry shrinkage of cement based materials containing ultra-fine fly ash;
