gritstone

After a brief description of the design feature and rock breaking mechanism of the disc one cone bit, the rock breaking process, test data and dynamic curves of a rock penetration test on a gritstone are introduced in detail.

在简述盘式单牙轮钻头的结构特点和破岩机理的基础上，详细介绍了这种钻头在资中重二砂岩上进行台架试验的破岩过程、试验数据和动态曲线。

It has strong surface effect, looks like the gritstone after efflorescence.

具强列的表面质感，如同风化过后。

Through the researches, we found that raw material of high silicon low alkali gritstone composition and high alkali clay composition had been calcined under 1400 ℃, so f-CaO in clinker is lower than 1.0%, even lower than this number.

通过试验研究发现，高硅低碱砂岩配料和高碱粘土配料两方案的生料经1400℃煅烧后，熟料中的f-CaO均在1.0%以下，且远低于这个数。

The Artux Formation is dominated by sandstone and siltstone, with minor gritstone layers, indicating a fluvial and distal fan environment. There are terrigenous clastic rocks and carbonate rocks in those Formations.
