Adopting the technology of modification of calcium lignosulfonate to develop a kind of hydraulic green high performance concrete(GHPC), which is of good durability, workability, mechanical properties, adaptability, stability in volume and rationality in economy, has been carried out.

These factors include not only three kinds of water reducers, that is, the modified calcium lignosulphonate high-range water reducer GCL1-3A, calcium lignosulphonate water reducer and naphthalene high-range water reducer FDN, but also dosage of water reducer, water-cement ratio, cement-sand ratio and the grade of cement.

The film forming mechanism of a novel calcium modified phosphating solution on galvanized steel was studied.

Application of NMR in wood modification

Based on the causes of wood creep,wood modification was put forward to decrease creep deformation of wood.

To provide reference for further study on wood modification ,this paper summarizes the results of research on wood modification including color improvement, softening, size stab.
