对, 按就是打算这么弄。 但用 12X12寸的 step stone. 代替小红砖。 这个大点。
因为另一侧俺要填高泥土。 每一块大概斜放 30度, 一块挨一块。 底下就斜插在水
泥里面, 所以水泥要加一根rebar 来加固。 3/8 rebar 对这来说太粗了。

好的。 俺去买个。 要做一个 raised flower bed. 上 rebar with cement.

可能跟不同地方的地质有关吧,也跟不同contractor有关,主要还是看你的driveway是
不是要heavy load, 停重型卡车什么的。我看到的铁丝网+fiber mesh的组合是承重更
好的。一
般driveway base比较好的,unreinforced 5" concrete slab都行。至于fiber mesh V
.S. 铁丝网,我不知道。至于rebar 肯定成本更高,有的地方code规定driveway入口是
不能用rebar的,估计这个跟水泥的厚度都有关系,4“的slab里面放rebar更容易crack
吧。我查到的是:Fibermesh can be used in residential, commercial or
industrial applications as the primary form of reinforcement without a rebar
skeleton.

来自主题: Living版 - Driveway 选择水泥还是沥青
主要区别就是有的concrete contractor用rebar, 有的不用,有的用wire mesh, 有的
只用fiber mesh mix. 用rebar或者wire mesh可能会多收钱,但是rebar和wire mesh主
要是保证crack后整个水泥还连在一起,而且4-6 inch的水泥里用rebar或者wire mesh
也不一定好,因为水泥里有很多小石头。用fiber mesh mix在水泥里的contractor, 可
能更省事,但一些研究说fiber mesh对crack有更好的抑制作用。我都用过,看不出具
体哪个好,wire mesh更old school一些吧,但可能贵。

Steel has an expansion coefficient nearly equal to that of modern concrete.
If this were not so, it would cause problems through additional longitudinal

concrete, it can still be pulled out of the concrete under high stresses,
an occurrence that often precedes a larger-scale collapse of the structure.

Make sure rebar is in the middle (not too low), make sure they do not pour

if you want it to last, 5 to 6 inch with rebar or steel wire mesh. make sure
it is in the middle not sink to the bottom when you pour the concrete, you
can use a hook to pull them up if they do sink, but it is better to build a
