Intended Audience: civil engineers and construction professionals looking for an introduction to soil grouting technology
PDH UNITS: 3
Grouting is a widely used method for strengthening and sealing rock, soil and concrete. The possibilities for sealing structures are of great importance from both an economic and environmental point of view. The cost of grouting has in certain projects been as high as the cost of blasting and excavating the tunnel. To improve the technique for grouting with cement-based material, it is necessary to examine the properties of the grout mixture used. This course is intended to provide an introduction to soil grouting materials and procedures for those engineers not familiar with the technology and its application. In planning a grouting program for particular conditions, the engineer needs knowledge of the various types of grouts and their properties. The basic types of grouts now in use and their properties and applications are discussed. Types of admixtures and fillers used and their effects on the grout are also discussed. The most common types of grouts are Portland-cement, clay, chemical, and asphaltic grouts. No one grout is suitable for every situation. The properties of each specific grout make it desirable under certain circumstances. Course Outline I. INTRODUCTION II. PORTLAND-CEMENT GROUT A. Portland-Cements B. Mixing Water C. Fillers D.
