Research shows that the crack resistance could be increased by improving the interface transition zone, using high quality aggregate, increasing concrete strength and adding the admixtures.

研究表明：改善碾压混凝土的界面过渡区，提高混凝土用水泥韧性，选用优质骨料，提高混凝土的强度及添加外加剂可以提高碾压混凝土的抗裂性能。

And the Stone Enveloped with Cement can meliorate distinctly the structure of the transition zone of interface, thus the strength of concrete is improved.

“净浆裹石”搅拌工艺可以大大改善界面过渡区结构，从而提高混凝土的强度。
