chuckey said:While every one is familiar with the sand on a beach, sand for building purposes should be of mixed grain size ( BS 1199 and 1200) and the grains should be "angular"- ragged not like "mini" pebbles. This way the sand particles lock together easily and the lime or cement mix is stronger when set.
As Lime is about 1/5 the strength of cement, its importent not to sacrifice even more strength by using poor sand.

What is impropper about sand from the Ure? It is a very fine river and the builders must have been able to recognise a good supply of sand to bother shifting it as far as half a mile. They may have needed a horse and cart rather than just a hand-barrow.chuckey said:When they try mine , they change to it. The cottages were built with sand dredged up from the river Ure (about 1/2 mile away). If they had built the cottage using the proper materials or materials in the proper way, I would not have to do the work I am doing now. Frank
