Building Construction Part 2 — making cement stabilized Adobe bricks

We have seen Dr Yogananda’s work on stabilized adobe in his office in Bangalore and thougth it is an interesting technique to try out. A mix of soil, sand , cement [added as a stabilizer – usually from 5 % to 10% by weight of the mix] and water is mixed and pugged before being shaped in a mould by hand and then cured by adding water for 3 weeks . The following pictures show the process.

Building Construction Part 3 — Learning basics of Brick Masonry

Now that brick making has been learnt, the next step is to learn to build a wall with bricks, so a few sessions on understanding basics of masonry were held. For this burnt bricks and a simple sand mortar [just sand and water and no soil or cement, so that it is easy to take the bricks apart after the session], were used.

Building Construction Part 4 Building the wall of cycle shed

Once the basics were clear, it was time to start applying what was learnt…. so went back to the cycle shed construction and after doing the fouldation out of stone and mud, decided to buid the wall. As a first step we thougth we will learn one more technique of using mud for wall and this is the Rammed Earth Wall. We made a mix of Soil, sand, cement and slaked lime [burnt lime stone added to water]; and the resulting mix was compacted inside a box kept on the wall. This rammed portion can been seen on the lower part of the wall in the pics below.
