This paper has arrived at the compressive strength, shear strength, modulus of elasticity, poisson's ratio, moisture content, water absorption and softening factor of lime-sand brick masonry.

The fact that specific absorption of aggregate has important effects on the optimum proportion of asphalt is detected by the tests.

The results showed that the super absorbent polymers added in ammonium bicarbonate could obviously promote the absorption of nitrogen, phosphorus oxide and potassium oxide by maize plants.
