Site Execution

  GROUTING PROCEDURE OF RETAINING WALL:-   Construction & Honeycomb Treatment:-        Chasing open the joints in ‘’V’’ shape/ ‘’U’’ shape groove of required width and depth as per site conditions. Chasing open the junction of RCC and the masonry surfaces, sealing the groove with repair mortar C:M with Conplast WL equivalent @ 150 ml per bag of cement etc.    The minimum dosage is 125ml and the maximum is 200ml per 50kgs of cement. If maximum dosage is used a minimum of 15% water should be reduced to ensure no loss in strength. The required quantity of Conplast WL is measured and stir into the first or second bucket of water. Conplast WL water mixture shall be added to the concrete or mortar and mixed thoroughly. Mixing shall be continued and further water shall be added until the required work ability is obtained. Grouting:- Cementious Grout:- ·     Providing and applying neat cement slurry grouting (Cebex 100) including expandable additive as directed by consultant

  HOW TO PREPARE SURFACE FOR WATERPROOFING :-     All surface area should be cleaned well to make visible of hair cracks / aggregate texture and opened the all the joints and construction joints.   Cleaning of RCC member should be done by hacking tool, wire brush, wire grinder & air blower etc. Make sure all kind of dust particles, oil & grease should be removed properly  ·          All visible cracks & construction joints should be sealed with cement mortar with additive Conplast  WL after making V groove.             All clean & treated area should test for water tightness by flooding water for minimum 75 mm head for 48 hours.     All wet spots, water leak & honeycomb areas should be mark for treatment. It shall be treated with        injection grouting with Cebex 100 as additive to be added in grout cement slurry @ dosage of 225         gm.  of packet per bag of cement or micro concrete. ·         Areas to be grouted should be prepared to ensure substrates

Concrete :- Concrete is a composite material defined as the mixture of cement, sand, coarse aggregate and water. Which is used for construction of building, infrastructure etc. The function of ingredients of Concrete:- 1:- Cement:- Cement is the most important ingredient of concrete. It is used to bind the aggregates, fine sand and coarse sand. 2:- Water :- Water is used for the lubrication of the aggregates and to cause chemical action with the cement called hydration. Water used in concrete should be potable without any inpurities. Clean water should be used in concrete. 3:- Fine Aggregates:- The aggregates which can pass through the IS sieve No. 4.75 are called fine aggregates. It's used to make concrete dense by filling the the voids and gaps of coarse aggregate and also to reduce the shrinkage of the cement on hardening. The use of the fine aggregates to make the concrete mix economical. 4:- Coarse Aggregates:-   The aggregates which pass

Ultrasonic Pulse Velocity Testing is non destructive technique which is used to check the quality of Concrete, In this method of testing we identify internal cracks, voids, strength and compaction quality of the concrete structure.  In this method we find out the velocity of pulse inside the concrete.   The higher velocity shows the good quality and lower velocity shows the bad quality of Concrete.     Velocity can be calculated by formula:-  (V)  =   Distance b/w trns. & rcvr. (L)    /                     Reading of machine or time take                                      by pulse (t) There are three methods of Ultrasonic pulse velocity technique.   1:- Direct Method 2:- Semi Direct Method  3:- Indirect Method 1:- Direct Method:-   This method is more relaibale and accurate. In this method we place the tansducer on one end and on other end we place the receiver. As shown in Image:-  2:- Semi Direct Method:-  This method is not as accurate as direct Method,

Cement:-  Cement is a building material, which is used as a binding material in construction work. It has cohesive and adhesive properties. Types of Cement   Pozzulana Cemen White Cement White Cement Quick Setting Cement Rapid hardening Of Cement Low Heat Cement  Expanding Cement High Alumina Cement Blast Furnace Cement Acid Resistant Cement Sulphate Resistant Cement Fly ash blended Cement 1:-  Pozzulana Cement :  Pozzulana is a volcanic power found in Italy. It can be processed from shales and certain types of clay also. In this cement pozzulana material is 10 to 30 per cent. It can resist action of sulphate. It releases less heat during setting. It imparts higher degree of water tightness. Its tensile strength is high but compressive strength is low. It is used for mass concrete works. It is also used in sewage line works.   2:-    White Cement :  The cement when made free from colouring oxides of iron, maganese and chlorium results into white cement. In the manufacture o

A bridge  is a man made structure built to avoid physical obstacles without closing the way underneath such as a valley,  body of water, or road, for the purpose of providing passage over the obstacle, usually something that can be detrimental to cross otherwise. Types of Bridges:-    There are basically five types of Bridges. 1:- Suspension Bridge 2:- Cable Stayed Bridge 3:- Beam Bridge 4:- Truss Bridge 5:- Arch Bridge   1:- Suspension Bridge:-  A suspension bridge is one of the most popular bridge designs. It features a cable support system that distributes the weight of the bridge deck between the two towers. The tension forces in the cables are converted to compression forces in the piers that then extends all the way to the ground. 2:- Cable Stayed Bridge:- Basically cable stayed bridge is a bridge that consist of one or more than one pillar with cables supporting roadbed. 3:- Beam Bridge:-   A beam bridge consists of a horizontal slab supported at each end

 Hello guys,                 In this video I am going to explain you about green building basic concepts, advantage and disadvantage of green building, how green building works.

Civil engineering  is a professional engineering in which we deals with the design, construction, and maintenance of the physical and naturally built environment, including works such as roads, buildings, bridges, tunnel, canals, dams, airports, sewerage systems etc.  A Building  is permanent or temporary structure enclosed within exterior walls and a roof, and including all attached apparatus, equipment, and fixtures that cannot be removed without cutting into ceiling, floors, or walls A road  is a long piece of hard ground which is built between two places so that people can drive or ride easily from one place to the other. A bridge  is a man made structure built to avoid physical obstacles without closing the way underneath such as a body of water, valley, or road, for the purpose of providing passage over the obstacle, usually something that can be detrimental to cross otherwise. A canal  is a manmade waterway that allows boats and sh
