What are liquisolid tablets?
Liquisolid system is a novel concept of drug delivery via oral route. This technique is applied to water insoluble drugs and lipophilic drugs to sustain their release. It involves dissolving the drug in suitable non-volatile solvent and then adding this liquid medication to the mixture of carrier and coating materials.
What is Liquisolid compact?
Liquisolid compact is one of the emerging techniques that enhances the dissolution of poorly water soluble drugs.
Which material used to increase pay off of compact?
The aim of this study was to improve the dissolution rate of the poorly soluble drug valsartan by delivering the drug as a liquisolid compact. Liquisolid compacts were prepared using propylene glycol as solvent, Avicel PH102 as carrier, and Aerosil 200 as the coating material.
Which cement is used for repairing cracks in RCC?
Dry mix shotcrete is most applicable in the repair of concrete elements. In such applications, an appropriate epoxy adhesive is also used to assure proper strength between the surface of the damaged structure and the shotcrete mix.
Which of the following is are types of mortar repair material?
Many types of mortars are used to repair structures.
- Portland cement mortar.
- Polymer modified cement mortar.
- Epoxy mortar.
Is the simplest & most common method of crack repair?
Stitching the Cracks is the easiest and long-lasting method of repairing concrete cracks. In this method, a number of the hole drilled along the crack surface and stitched with metallic wire.
Which causes of failure of RCC structure?
A reinforced concrete member can fail mostly in the following cases: When the concrete is subjected to excessive shear. On account of the slipping of the steel bars from concrete. Due to bad quality of materials used that can cause shrinkage creep or thermal effects.
What is grouting material?
Grout is a composite material generally consisting of water, cement, and sand. It is typically used for filling voids under machines or other structural elements, sealing joints and openings in surfaces and reinforcing existing structures.

What are repairing techniques?
Repair techniques included are: acid etching, caulking, coating, conventional replacement plastic and dry pack; grinding or grooving; injection; jacketing; prepacked concrete; resurfacing thin, regular, bonded or unbonded; shotcreting; stitching; and stressing.
What are the common modes of failure of RCC building?
Case 1: Failure of RCC Column Due to Corrosion of Reinforcement. Case 2: Failure of Building Due to Improper transfer of load. Case 3: Failure of Reinforced Concrete Structure due to Poor concrete mix and water quality. Case 4: Failure of RCC Structure due to use of Beach Sand in Construction.
What is failure RCC structure?
A reinforced concrete member can fail mostly in the following cases: When the member is subjected to excessive tension, so as to exceed the permissible stress in steel. When the loading is such that the compressive stress in concrete exceeds its safe permissible value. When the concrete is subjected to excessive shear.
