Purpose of slump test for concrete?
To check the consistency of the concrete; to determine if the concrete flow smoothly into the shape of the formwork. It is a quick check to see if the concrete is suitable for use.
Can you use a dirt wall as a form when pouring concrete?

What is the use of lean concrete?

What is the difference between Structural Concrete and Non structural Concrete?
Structural concrete is used in the construction of buildings, bridges, dams, etc. Typically there are more codes governing the use of concrete as a construction material and the concrete used has higher strength. Non-structural concrete is typically defined as being used for the construction of non structural elements. These could be parking lots, sidewalks, handicap ramps, etc. A lower strength concrete can be used and there are less rules pertaining to its use.
Why does not use other material instead of steel for concrete work?
Because of the thermal compactablity of the steel the material is used in concrete
When did pa. cemeteries start to use concrete burial vaults?
Concrete burial vaults began to be widely used in Pennsylvania cemeteries in the mid-20th century, particularly after World War II. The shift towards these durable containers was influenced by the desire to protect gravesites from ground settling and to meet evolving burial practices. By the 1960s, the use of concrete vaults became more standardized across many cemeteries in the state.

How heavy and how expensive are grave vaults?
Very Maybe, but it depends, because there are big differences both in weight and in price. p { margin-bottom: 0.25cm; line-height: 120%; }a:link { } Price and weight of burial vaults largely depend on the materials used; weightwise, protective burial vaults range from approximately 100 lbs upwards (plastic vaults) through 400 lbs and more (12 ga steel) and 2,000 to 3,000 lbs (composite vaults, made of a combination of concrete and other materials) to 3,800 lbs (bronze lined concrete vault). Minimum prices vary from US $700 (reinforced concrete vaults) respectively $ 1,000 (metal and composite vaults) to $ 24,000 (bronze composite vault). Prices for non-protective concrete grave liners (weighing 1,500 lbs or more) are usually lower than for protective vaults and start already at $ 600. The terminology might be somewhat confusing and needs therefore some explanation. Burial or grave vaults in the widest sense are outer burial containers for the casket. In the narrower sense of the word, vaults are hermetically sealing (air- and watertight) outer burial containers, while non-sealing (non-protective) containers are called grave liners or grave boxes. While no state law requires the use of a grave liner or vault in the US, many cemeteries do. The primary function of the outer burial container is to prevent the grave from sinking and caving in as a result of the weight of the earth pressing on the casket and of the use of heavy cemetery maintenance machinery. This function can be fulfilled very easily by a simple concrete grave liner. A burial vault fulfills the additional function of protecting the casket from the elements, especially from ground water. For this purpose, vaults can be sealed: the use of lining and sealant materials merge the box like base and the "flat" cover (lid) of the vault into an air and watertight unit which protects the casket. Metal vaults, which usually have a "flat" base plate upon which the dome shaped vault is placed, protect the casket by allowing air pressure to build up in the dome, keeping moisture out.Some vaults are very expensive, indeed. The most expensive and heaviest grave vaults currently manufactured in the US probably are:- the 10ga (108oz) copper Custodian, a metal vault made by the Clark company, weighing around 600 lbs and being offered at prices around $ 16,000 retail- the 90oz triple-walled bronze and concrete composite vault by Wilbert, which weighs 3.800 lbs and is offered at prices between $ 8,000 and 16,000- the Doric Olympian Bronze composite vault which consist of a concrete core and has an 48oz bronze outside and a 16ga inner bronze liner, resulting in a weight of 2,900 lbs and costing some $ 24.000.
