NEW DESIGN OF MASONRY PANELS USING MURFOR COMPACT.

"BED REINFORCEMENT ON A Roll"

As construction has become more competitive, the walls have become thinner than they were half a decade ago.
This caused problems for the designer, the contractor and the owner; there is less reserve of force to respond to movement for example. Non-clay walls tend to move due to changes in moisture content and, with certain combinations of shape and size, cracks appear in reinforced walls.
Murfor is the new generation of masonry reinforcement. Supplied in a roll, this reinforcement is extremely user-friendly and guarantees effective and lasting protection for your masonry, incorporated into bed joints, can virtually eliminate the development of unsightly cracks.
Thin walls are more difficult to justify for lateral loading, and Murfor can greatly help their ability to withstand such loading.

BASE ISOLATION SYSTEM:

Base isolation may be a sort of system within which the super-structure is isolated from the bottom structure(foundation) by a suspension.It sounds terribly easy however in sensible it is not. Base isolation system is usually wont to scale back the bottom vibration(caused by earthquake) which will cause harm to the structure. This system really helps to cut back the frequency and magnitude of the bottom vibration(caused by earthquake).

IMPORTANT TYPES OF FORMWORK USED IN CONSTRUCTION SITE:

Formwork is a mold or open box, like a container in which fresh concrete is poured and compacted. When the concrete is set, the formwork is removed and a solid mass is produced in the form of the interior face of the formwork. The top of the formwork is normally left open.
Temporary formwork designed to be struck and reused may be made from any economic and easily worked material, timber, steel and GRC/GRP being the most common.
Formwork materials can be classified as:
1- Timber Formwork
2- Metal Formwork
3- Plastic Formwork
4- Insulating concrete form or insulated concrete form (ICF)

FLAT SLAB BUILDING STRUCTURES POSSESSES:

Flat slab building structures possesses major advantages over traditional slab beam column structures because of the free design of space, shorter construction time, architectural functional and economic aspects. Because of the absence of deep beams and shear walls, flat slab structural system is significantly more flexible for lateral loads then traditional RC frame system and that make the system more vulnerable under seismic events.
The results of the analysis of some types of building systems presented in the article show that the system of flat slabs with certain modifications (design of the beam in the perimeter of the building and / or the walls RC) can reach a factor of rational behavior considering EC8 and can be considered as a system with acceptable seismic risk. Modifications with additional building elements improve the low load bearing capacity of the system and increase strength and rigidity, thus improving the seismic behavior of the flat slab construction system.

"GREEN CONCRETE" AGAINST GLOBAL WARMING

24/02/2020

"GREEN CONCRETE" AGAINST GLOBAL WARMING:

A German researcher has developed a new type of concrete called "green concrete". This new concrete is mainly based on a new type of cement characterized by many advantages, from the point of view of the environment, compared to traditional cement known to man and on which it relies for decades. The new cement is manufactured in one of the main industrial facilities of the German Institute of Technology KIT in Karlsruhe. The new cement, named by the owner of "cement", is also manufactured in less calcareous quantities. Stimmerman. Since Stimmerman developed the method with the help of three colleagues after 15 years of preliminary research, companies and businessmen came to him from all sides.

What Is The Difference Between Nominal Mix And Design Mix?

NOMINAL MIX.
1- When concrete is produced using standard arbitrary proportions of concrete ingredients, it is known as nominal mix concrete.
2- The nominal mixture is a mixture taking into account all the ratios in the volume where the strength and cost of concrete and the strength of concrete vary.
3- It is concrete of the prescriptive type.
4- It is used in ordinary concrete involving a quality of concrete not higher than M20.
5- There is no quality control.
6- The water-cement ratio is based on sustainability criteria, experience and practical tests.
7- The water content can be modified by the slump value (field test)
8- No trapped air content is taken into account.
9. The concept of test mixtures is mentioned.

DESIGN MIX.
1-It can be defined as the process of selecting the appropriate ingredients of concrete and determining their relative proportions in order to produce concrete of a certain minimum strength and durability in the most economical way.
2- The design mix is ​​a mix considering that the whole mix ratio is by weight where the strength of the concrete is a constant cost of the concrete which can be reduced.
3- It is concrete based on performance.
4- It is adopted for high quality concrete.
5- It has quality control.

PILE FOUNDATION:
Pile foundation support the structure, transfer the loads from the structure to the ground. However, the layer to which the foundation transfers the load must have an adequate bearing capacity and appropriate settlement characteristics.

TYPES OF PILE FOUNDATION:
1- Based on material Used
2- Based on Mode of transfer of Load
3- Based on the method of installation
4- Based on Uses
5- Based on the displacement of soil
6- Under-reamed Pile

CAUSES OF FAILURE OF PILE FOUNDATION:
1- Inaccurate determination of the bearing capacity of the pile.
2- When the pile load is greater than the design load.
3- Poor and defective workmanship while casting the pile.
4- Corrosion of the timber pile because of assault by insects.
5- Defective techniques used while driving the pile.
6- Bearing pile laying on delicate strata.
7- Buckling of the piles because of insufficient lateral support.
8- Faulty soil investigation.
9- Selecting the wrong type of pile.
10- Inappropriate characterization of soil.
11- Inadequate reinforcement in the pile.
12- A decay of piles. (like an attack of insects, corrosion etc.)
