This dependence on importation of foreign products whose raw materials abound in the country is a major drawback to the economy [4].
Clay and shale which occur abundantly in the sedimentary basin of south eastern Nigeria, including parts of Edo and Delta States are vital raw materials needed for the manufacture of a wide variety of products [5].

The test procedure and materials are also rarely studied.
The reasonable test methods including test procedure and materials characteristics etc. are also studied.
Figure 1 Test device for low temperature adhesion test Materials and experimental program Three types of aggregates were used in this study, which including granite, limestone and basalt.
And the aggregates with 6-8mm were finally determined to be the test materials.

Introduction Tobacco leaves are the important materials in tobacco production.
Traditionally, these materials are only used as the fuel to liberate heating energy, which is not only less effective but also creates an environmental related problem.
Experimental Materials and reagents Tobacco stem and tobacco dust were supplied by China Tobacco Guangdong Industrial Co., Ltd..
Hot water extraction of tobacco stem and tobacco dust Tobacco stem and tobacco dust were extracted in a 15L rotating digester with 1200g of raw materials.
