How to get rid of concrete crack by using construction joints

Construction joint, expansion joint, contraction joints and isolation joints are the four types of joints generally found in Concrete Construction. They prevent the concrete from cracking. To get the optimum result, the exact position should be clearly identified before placing the construction joints in a concrete slab. Additionally, there are several types of joints in Concrete Structure, as stated below.

Materials for joints in water retaining structures and water tight structures:

  • Materials for joints in water preserving structures and water resistant structures for sewage and wastewater treatment will safeguard the construction from ethereal and close microbiological attack as well as gasoline, diesel oil, dilute acids and alkalis like hazardous materials.
  • Materials for joints in water preserving structures for drinkable and fresh water will adhere to the obligations of BS 6920.

Joint filler: Joint filler should be solid, elastic, single-thickness, non-decaying filler. Full depth of joint filers is designed to protect the joined ends. Joint filler for joints should be waterproof in water preserving structures and water repellent structures.

Bitumen solution: Bitumen composite for joints in water preserving structures and water-repellent structures will adhere to BS 3416. Bitumen composite for surfaces alongside which drinkable or fresh water will be preserved or transmitted, should adhere to BS 3416, type II.

Joint sealant: Joint sealant provides an effective and durable solution in concrete construction.

 

Joint sealant will maintain a grade to cope with the environmental conditions of Hong Kong and work perfectly over a temperature range of 0°C to 60°C. Joint sealant will remain grey for exposed joints.

 

Joint sealant except cold-applied bitumen rubber sealant will contain the following:-

 

  • A gun grade intended for horizontal joints, vertical joints and for disposed joints and having length 15 mm wide or less.
  • A pouring grade for horizontal joints having span over 15 mm.

 

Polysulphide-based sealant refers to a cold-applied two-part sealant that adheres to BS 4254. Polysulphide-based sealant meant for expansion joints in water preserving structures and water-resistant structures must contain a minimum 20% transverse butt-joint movement.

 

  • Polyurethane-based sealant refers to a cold-applied two-part sealant that adheres to the performance requirements of BS 4254.
  • Hot-applied bitumen rubber sealant shall compliant with BS 2499, type N1.
  • Cold-applied bitumen rubber sealant will be similar as proprietary type.
  • In table 1 given below, the description of Joint sealant for joints in water preserving structures and water resistant structures is provided.
  • The joint sealant manufacturer approves Primers and caulking material, to be applied with joint sealant, should be proprietary type.
  • Different types of joint sealant and primers which are combined with each other, will be congruent in nature.

 

Bond breaker tape: The Joint sealant manufacturer and the Engineer recommended and approved the Bond breaker tape like a proprietor type. The Bond breaker tape refers to a polyethylene film containing adhesive on one side and remains to be the complete width of the notch.

 

Bearing strip for sliding joints: The engineer recommended the Bearing strip for sliding joints that encompasses two plastic strips of a proprietary kind. These two plastic strips will protect from all weather conditions as well as chemicals to which the construction will be dependent devoid of weakening the reaction, sturdiness or utility of the strips.

 

Once it is set up, no maintenance work is required. The strips can combat with a vertical load of atleast three hundred kN/m2 and contain a most stable friction of 0.3 under a persistent cutting off force.

 

Water stops or Water stoppers: Water stops will range from natural or plastic rubber or extruded polyvinyl chloride and shall consist of the properties of density, hardness, lastingness, water absorption. Water stops, as well as intersections, educers and junctions, shall be of a proprietary type as recommended by the Engineer.

 

Construction joints are formed with the use of the specified materials. It will ensure that a better perception of material and proper choosing of water proofing material for various water retaining structures consisting of a durable waterproof system.

Materials for low cost house construction

Low Cost Housing is a concept of reducing the construction cost in the construction Industry through the use of locally available materials with new technology and upgraded skills. In low cost housing building material cost is less but it does not mean that these buildings are constructed with cheap building materials of low quality. However low cost housing is done by efficient planning and proper management of resources. Low cost housing helps the low income group peoples to accommodate themselves into the buildings with minimal cost. This low cost housing can be developed with low cost building materials and low budget.

How to choose materials for Low Cost Housing:-

A few steps are taken at the time of choosing materials for low cost housing. The life cycle of building or housing is going through by three steps, i.e. pre-building stage, building stage, and pro-building stage. These three stages signify flow of building materials via diversified phases of a building. Pre-building includes processing, packing and transportation which are part of manufacturing process. Building stage consist of construction, operation and maintenance. And, in the pro-building stage the materials are recycled or further used.

Each stage of building is formed in such a manner so that the energy can be preserved for the building.

Pollution Prevention: Raw materials for housing are extracted from the ground or harvested from forests to reduce less pollution to the environment. Materials may emit additional pollutants during their production, installation or use. So at the time of manufacturing, building materials should be suitable and acceptable to the environment.

Biodegradable: When a material is disposed, it is dissolved naturally. Natural as well as organic materials are very easily dissolved. So while choosing a material, the precaution should be taken regarding whether a material decomposes naturally or generates some venomous gases.

Low embodied energy: Embodied energy is to define that energy required to construction materials, the process of building and after-effect on the environment. The reduction of the building industry’s energy consumption is of great importance and low embodied energy provides great solution in solving the issue of energy consumption.

Reuse and Recycling: Reuse and recycle of building materials effect the housing process, the circulation of materials or used materials. The roles of waste products within local and geographical boundaries become important deliberation for architects. Basically, scraps from plastic materials, steel are used to recycle for producing new materials.

Consistency of Building Materials: The consistent building material can provide a great impact on longevity and stability of the building as well as reduces the cost of maintenance. The reduced maintenance costs lead to saving huge operating cost of a building.

How to use RCsolver software program to make the design of 2-way reinforced concrete slab

Dimitrios Mamoglou, the renowned engineer and software developer, has presented an exclusive video for construction constructor & construction estimator. This video shows how to design a two way reinforced concrete slab through RCsolver software program by following Eurocode 2 specifications.

RCsolver is the kind of software that is used to create the design and computation of reinforced concrete structural members. It makes all the calculations defined in the Eurocodes and ACI 318-11 toward the tensile and shear reinforcement of the structural members.

RCsolver helps the users to have a 3D digital view of the members and the reinforcement rebars. It is combined with Eurocode 2 and 8 specifications, together with the national annexes specifications concerning a great amount of European countries. The latest version of RCsolver consists of the ACI 318-11 specifications focusing concrete member design.

Eurocode 2 and EC2 are both short forms for BS EN 1992, Eurocode 2: Design of concrete structures. There exist four parts to BS EN 1992 but while referring to Eurocode 2 a good number of people suggest BS EN 1992-1-1 general rules and rules for buildings.
