Silence is not Automatically Golden

Introduction to marketing professional Services Marketing professional engineering services is a relatively new profession, dating back approximately 2 decades. Allied to product marketing, it is, nevertheless, quite distinct. It could be described as the ‘art of selling a promise’, as there is nothing tangible to review on the purchase, and the drawings and specifications are conceived, formed, shaped, and finalised, only after the client has ‘bought’ the service. C. Shearer

Concrete with densities between 800 and 1200kg/m3 can be produced using lightweight aggregate in a foamed cement matrix, They have cube strengths in the range from 4 to 16N/mn2. They offer considerable weight saving and significant thermal insulation, combined with strengths sufficient for many structural purposes. Reinforced elements made of such materials behave in very much the same way as members of normal dense concrete. P.E. Regan and A.R. Arasteh
