Why should aggregates be added to cement? How do they affect the strength of concrete?

Aggregates are classed as inert materials as they do not enter into complex chemical reactions with water. Aggregates are usually classified as fine and coarse aggregate. Their characteristics like size, shape, surface texture, grading (particle size distribution) and mineralogy affect concrete strength in varying degrees. Concrete mixtures containing larger aggregate particles require less mixing water than those containing smaller aggregate. However, larger aggregates tend to form weaker transition zones containing more micro cracks. A change in the aggregate grading without any change in the maximum size of coarse aggregate, and with water/cement ratio held constant, can influence the concrete strength when this change causes a corresponding change in consistency and bleeding characteristics of the concrete mixture. A concrete mixture containing a rough-textured or crushed aggregate would show somewhat higher strength at early ages than a corresponding concrete containing smooth or naturally weathered aggregate of similar mineralogy. A stronger physical bond between the aggregate and the hydrated cement paste is assumed to be responsible for this. Differences in the mineralogical composition of aggregates are also known to affect concrete strength. Top

What is the difference between built up area, super built up area, and carpet area? 

Carpet Area is the area of the apartment/building which does not include the area of the walls.

According to Vasthu Shastra there are three forces in action to create harmony. Wind, water and fire or, vaayu, jal and agni. If these forces are kept in their appropriate places, then there will be no disturbance. But if water is put in place of fire and wind in place of water or in any other combination, the forces will start acting accordingly and create disharmony. Top

Vaasthu Shastra is an ancient science-cum-philosophy, based on astrology and Hindu divinities, developed by the sages of yore to ensure good fortune for the home builder and dweller. It aims at providing guidelines for proper construction. Its a study of planetary influences on buildings and the people who live in them. Top

The plot you mentioned is a highly negative one. The fundamental factor of the levels explained by me can never be achieved in such plot. Since the slope looks to be very steep, it is almost impossible to correct the plot to make it vastu complaint. The difference in levels look to be around 40 feet. As per vastu this plot may create major financial set backs and hamper the growth of the owner. When we consider all the other factors like architecture and engineering, looks and views cannot substitute to create a good vastu plot. How ever as we are not able to consider any of the vastu features to a satisfactory level, the advice is to reject the plot and should not be used for any house. Top

There are specific principles to be followed for constructing a house with pillars. The total number of pillars must be even numbered without ending with zero. That means 8,12,14,16 etc. are allowed where as 10,20,30 are not allowed. No pillar should be allowed to be hanging. That means every pillar must have an opposite pillar either in vertical or horizontal directions. The pillars, which are located in the northeast zone, must not be round. If at all they have to be taken round for elevation purposes, they must be having square or rectangular foundation and square or rectangular ending at the roof level. Incidentally, vastu also specifies about the number of beams and types of beams that should been used. They must be even numbered as in the case of pillars. Top

As a general rule expansion of existing business establishments will create problems. As such there are specific considerations to be taken case of while expanding towards south or west. In your case since there is a hillock in the southwest corner, expanding towards south will create problems. The entire southern portion will become a reversed slope area, which is considered as highly negative. Expanding towards west will also create problems because the southwest corner will become lower than the southeast area, which is right now having a hillock. Reversing these heights will pose a greater problem and financial expenditure. There are also heavy structures, which must be compensating if the western area is expanded. The newly defined southwest area must not only become high but also very heavy as far as the usage is concerned. So expansion towards north or east in your case is more desirable and will be as per the vastu principles. Care must be taken to correct the levels as compared to the existing plot. The compound walls and other areas of the new plot must be considered for the location of bore wells and water sumps. They must be relocated in the proper northwest zone of the entire plot. Similarly, the transformers or generators also must be relocated in the newly created southeast zone. Top

I have examined you plot and details of house. As this is a diagonal plot, care must be taken to follow specific vastu rules. There is no choice of taking any liberties with the construction aspect of the house. The road, which is a busy one should be treated as the one containing north, northeast and east directions. Hence the nalah should be treated as forming a part of northwest zone. Though this is negative, it may be positive in some portions of the year.
A. The main entry must be taken from the main road, as this is the powerful zone in the entire plot. The main entry can be left or right side of the front wall. For excellence results it can also taken in the exact centre of the front side. The modern layout of the rooms is in such a way that the cen6tral entry will not be a proper internal arrangement. Hence it is better to take on the right side as this is nearer to both roads.
B. The plot can have series of rooms towards southwest side, which is forming the centre of the backside wall. Care must be taken to have the doors exactly opposite the main door.
C. There can be a side door towards the small roadside. This can be always used as a secondary door only. It is better not to take any doors towards the nalah side. For the moment that side can he restricted to minimum as this can affect health wise also.
D. Avoid taking the first room and last room for kitchen. The first room can be a formal drawing room or living room. The last room can be taken as the master bedroom. Each room must be maintained as a perfect square or rectangle.
E. The attached toilet for the rooms can be taken in the northwest or southeast or south side of the room. Even these toilets should be part of the rectangular rooms only. There should not be any extensions to the rooms for any purposes.
F. The staircase can be taken in the entire backside of the house that is the southwest side. Any construction must not touch the compound walls of the plot in any way. Top
