A literature survey concerning the addition of locust bean gum to beaten pulp and the resulting strength characteristics imparted to handsheets through the addition of the gum has been undertaken. Although much literature can be found, hardly any detailed information can be extracted on the effect of alum or hydrogen ion concentration. Therefore, the aim of this paper is to draw some conclusion, through laboratory work, as to any possible change, due to pH or alum, in the strength characteristics of handsheets containing locust bean gum.

The first part of this thesis will be a brief review of work that has already been carried out concerning the use of locust bean gum in paper-making, while parts two and three will show the planning of experiments and results of the laboratory work.
