Dear reader in our previous posts we have discussed about advantages of soil block and additives used for soil stabilizing; here we will discuss about relative comparisons of different stabilizers.
We know cement, bitumen, lime and industrial by-products are used as stabilizers. Of these cement is most popular and used extensively. Soil that is stabilized with lime show less water resistant and less strength relative to stabilization with cement.
But both types of block can be produced; here more perfect word is compacted by Cinva Ram. Now what is Cinva Ram? It is a block making device, obviously block of stabilized soil.
Now we will learn about some block making devices. We have already introduced Cinva Ram other popular devices are
-Ellson block master.
Of these Astram can produce about 500 blocks on average. Production rate of Balram is about 1000 blocks. Again production means pressing stabilizer soil to desire shape, size and expected pressure.
The block size can be pressed by Astram is 23X19X8 cm, that of Balram is 23X11X7.5 cm.
The purposes of stabilizing are
-To increase bearing strength of soil block
-To improve their resistance against moisture or water
All stabilizers improve these properties more or less, one can improve strength but may have poor performance against water repellent property, some perform fair in both properties of block. Dear reader we will discuss comparison between cement/lime with bitumen and their usual treatment quality for soil block.
