Density of RCC is 25 kN/cubic m, and that of PCC (Plain cement concrete) is taken as 24.

Mix design would indicate that all the mixes being used would be subject to set design criteria.But a nominal mix would indicate a nominal or minimum or variable cement content as agreed with the engineer depending upon the location to be used.

Your question is not very specific. However, here are some information that might be helpful.\n\n1. If you are pertaining to fresh concrete, there is no specific record on the degrading effect of diesel. In fact, actual construction sometimes uses diesel based form release agents that debonds the fresh concrete from the formwork. Diesel is oil based. Knowing that, it will not in anyway mix or affect water content of the fresh concrete since oil and water repel each other. It may be important to note however, that there is no defined ACI or ASTM specification for the use of these form release agents. These materials are mostly regulated by EPA.\n\n2. In terms of concrete design, it is apparent that the main effect of diesel is its specific gravity. Diesel has a specific gravity ranging between 0.81 - 0.96 (based on water SG @ 60 deg. F. This means that you would not require as much reinforcement as you would in a tank that would store water.\n\n3. Some waterproofing materials that are used to protect concrete are diesel based. Again, this proves to show that diesel has no degrading effect on concrete.

In its simplest form, concrete is a mixture of paste and aggregates. The paste, composed of portland cement and water, coats the surface of the fine and coarse aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

Each anchor manufacturer will have a table for each style, but figure that means about 1 lb per foot for a pivoting-fluke anchor, or 2 lbs per foot for a yachtsman-type anchor.\n\nIf you just want to use a big chunk of concrete as a deadweight, you should have 2 of 150 lbs each.

#6 vertical bars @ 12 in centers with 90 degree bends top and bottom, #8 lap bars horizontal full length and a total thickness of 12 inches. 3000 to 4000 psi concrete with crushed rock and a water cement ratio of under .45 should do the trick.

TIME, TIDE AND CONCRETE WAITS FOR NO MAN.\nIt is poured insmall slabs because :-\n1.  it is easier to handle and maintain levels\n2. it will expand and contract more uniformly and lessen the chance of cracking occurring\n3. in large areas it enables falls of levels to be made in different directions for drainage  lines.\n4. in doing a big pour you have to ensure that you don't have to wait too long between loads as the first load could go off before you put down the last one.

Usually pascal's.  But it really would not matter because you are calculating a ratio in this instance and no matter what units are used for pressure the same ratio will be produced in this problem.

Hardened concrete strength depends on the water to cement ratio (w/c ratio). Lower the w/c ratio, higher the concrete strength. This is because excessive water in concrete may create water pores and void in the concrete which will affect concrete strength.\n\nBut the problem is when we use lower w/c ratio, workability of the concrete will be very poor. Increasing the use of water in other hand may improve workability but increases w/c ratio. By adding superplasticizers into fresh concrete, it can improve workability and maintain optimum w/c ratio.\n\nAlthough plasticizers cannot directly improve the strength of hardened concrete, it promotes workability, thus enable concrete to have lower w/c ratio.\n\nMore technically, superplasticizers interact with wet cement particles and produces a membrane of absorbed charged molecules around each particles, with prevent the cement from flocculate or become sticky.

Use the regular "concrete mix design" and add a "water reducing admixture".\n\nThe water reducing admixture type should be selected so that it does not require a reduction in the amount of "cement" that was in the original concrete mix design.\n\n(Note that a standard concrete mix design includes such things as __% of aggregate (rocks), __% of sand, __% of cement, __% of ash, __% of water, etc. and it does not normally include a water reducing agent.  It would be an additive supplement.)

Depends on what you mean by types.\n\nDo you mean the type of material used in constuction or the type of activity the building is intended for.\n\nMost large building use a chilled water system where they use chillers to cool water down to about 42 deg F then pump the water throught the building to air handler units which blow air across the coils filled with the water.  This heats the water, but cools the air.  As the air is circulated throughout the area the water is returned to the chiller to be recooled and the process starts all over again.\n\nHowever, an important point is capacity.  That will be determined by both what the intended use of the building is and what sort of material is used.

Cement is composed of five types of minerals such as  limestone, shale, silica, pyrite and gypsum.  Limestone were grounded from the impact crusher (mostly 1 cubic meter size) to as big as half the coconut shell, then it is will again passed through a jaw crusher from this size, it will be like 3/4". After this the lime stone will pass through the ball mill(a rotating drum consist of different sizes of ball metals) with other ingredients.  The product will be like a face powder.  \n(For Semi-dry process)\nThis face powder like shall go through a tilted rotating pan, where a tricle of water will make a sphere size as size as a marble. This sphere size mixture shall pass through the calcining stage(this is removing the moisture in it).  After the calcining stage, it will pass through a rotating kiln  at a temperature of about 2,700 degrees celcius.  This temperature is enough to burn and turn red your mixture(similar to volcanic lava).  The product of these is like charcoal and what you call clinker.  It will pass through the last process to make it cement.  Another ball mill(mostly this is called the finished mill) and with the same texture(face powder like) and mixed this with gypsum then you got portland cement.\nNow are you ready to turn the soil into like a volcanic lava?
