 The following steps explain how the mixing process was done.

o   Volume batching was carried out in this project .So the materials were measured by a 1 liter measuring jar. According to the particular proportion the materials were measured first and kept separately .This was done just before the mixing starts.

o   Glows, shoes, masks were weared before the mixing.

o   Then, the non–water absorbing and smooth surface was made for mixing.

o   Water was sprinkled over that surface. And this mixing place was selected nearer to the casting place.

o   First the ingredients like Sand/RHA/FA were placed.

o   Then cement was placed over that ingredient.

o   These two were dry mixed with shovel thoroughly still                                uniform colour was formed.

o   Then the paper pulp, which was in a wet condition was placed separately. Paper pulp should contain less water. So the excess water was squeezed out.

o   The already mixed cement and FA/RHA/sand was placed over the paper pulp and mixed thoroughly to get the uniform mix.

o   There was no further water was added separately unless it was essential. The water in the pulp was utilized for mixing the papercrete.

o   After the mix, the required amount of papercrete was taken to the site and the remaining amount was kept free from evaporation.
