With examples of petrochemical projects,the author introduces the importance and effects of doing the constructability audit in project design stage,and also states some aspects of the constructability audit such as personnel placement,responsibility,audit process,and design audit lists.

Nowadays there are so many problems in the management of large-scale construction, especially, the problem of constructability is become more and more important.

Experimental study on construction performance of premixed self-compacting concrete

By adopting fused dense corundum(FDC) and fused white corundum(FWC) as the main raw materials,the influence of active α-Al2 O3 micro powder and fused magnesia(FM) powder on the construction performance,m echanical performance and microstructure of RH-dipping tube castable was invest igated.

The results of the experiment and the project application indicated, for high performance and self-dense micro expansive concrete, the effect of expansion agent and chemical double-mix additives is better than the complex mode expansion agent in construction performance.

It proved that the coatings workability and physical appearance can be improved dramatically by adding thixotropic reactive resin for various colors coatings.

Compatibility of high belite cement, Portland cement and ordinary Portland cement with superplasticizer and effect of mineral admixtures on the compatibility of high belite cement have been studied with the test of the workability of concrete as reaffirmation.

Air entrance as one way to adjust mortar workability has been widely used.
