A.2.3 Roof Very little if any timber is used as construction material. Foam concrete, also known as Lightweight Cellular Concrete (LCC), Low Density Cellular Concrete (LDCC), and other terms is defined as a cement -based slurry, with a minimum of 20% (per volume) foam entrained into the plastic mortar. In particular the lighter densities of FC have an excellent thermal insulation value due to the high air bubbles content. They are made with a wall formwork mould system, and all the walls of one unit are cast in a daily cycle. In general, layouts must be simple. Although they do not function as the primary reinforcement, the fibres highly improve the quality by toughening the wall and by limiting surface cracking in the initial setting after casting. The insertion of foamed-concrete insulation can probability be automated. Concrete is one of the cleanest and most versatile types of wall material available. Steel bars are used to reinforce the walls according to Engineer’s specification. Foam concrete is a versatile building material with excellent properties. The roof in its simplest form can be with timber beams and corrugated zinc sheets. Steel windows and doorframe cast into wall (South Africa). The most suitable foundation is a reinforced dense concrete or foam concrete raft slab that together with the walls forms a strong and stable boxlike structure. The height of the walls should be conform the standard height of the mould panels: as a rule they come in standard height of 2.70m or with some systems 2.64m. Houses must be designed according to local Building Codes and Regulations , its structural aspects to be designed by a qualified Structural Engineer. In warm climates it is important to ensure ventilation under the roof (cross-ventilation) to prevent the roof space from heating up. Formwork in progress, technical installation being installed. I have long wanted to build my own home. In this age of conservation of resources and green, sustainable approach, these factors play an important role. Single wythe walls may incorporate foam insulation in the cores of the masonry units as either rigid foam inserts or foamed-in-place insulation. A.1.8 Lay-out and Design The finished wall will be 5.75 in. Foam concrete from Hasit-Schaumbeton is a mineral, non-flammable, 100 % recyclable and well insulated product – a perfect supplement to serial wall production with the BT innovation butterfly formwork. The panels are a sandwich of foam that has wire mesh on the outside and each side of mesh is connected to the other with mesh that goes through the foam and unites both sides. Ted Gorab Published: Oct. 3, 2019, 6:09 p.m. Last updated: Aug. 6, 2020, 11:52 a.m. Foundation Assembly line principles for the sequence of activities for preparation and work on the construction site. The required labour force can be mostly unskilled. These products are without exception of constant dimensions and of consistent high quality. Strictly speaking, no further finish is required. Because of the industrial charachter of the construction, a higher percentage of unskilled male and female workers can be employed. The molded foam blocks replace traditional forms and, since they remain in place after the pour, they provide excellent insulation and sound dampening qualities. Foam concrete has favourable properties such as high compressive strength, excellent thermal insulation, high fire resistance and low water absorption. In combination with a floating raft foundation a stable, strong box type structure is formed. FC does not use gravel and because of the high air content, uses less sand. Doorframes can also be installed after casting so only the required opening in the wall must be made in the formwork mould. Custom made panels should be avoided where possible as they are expensive, require longer production time and add to the overall cost. The houses can be built as basic house or as a more complete house; all houses though are very suitable for future upgrading and extending. If you are building by your self or with just one helper to save money in your spare time you don't want your site to have a half framed wooden building for too long as it could attract vandals. each side of the panels would be attached to each other by the steel tubing that is inserted into the foam. ICFs are just one part to your wildfire protection strategy. Concrete structures can be among the safest and most durable types of structures in an earthquake. An Idea for a DIY,Low cost, low maintenance, hurricane and fire resisitant home. By using modern construction methods, the quality of the built houses is mainly controlled by the system. Ventilation blocks can be incorporated in the mould and cast in. The walls of a FC house form a strong and interlocking structure. )the second advantage is I think the panels can be made and  assembled at home by a single person so you would not have to buy them from a company already assembled. Near coastal areas some zoning boards frown upon continuous concrete footers as they can dam up … The Disaster-Resistant Advantages of Insulated Concrete Foam. Worldwide there is an enormous demand for good quality, low cost housing. The design of the house should be based on extensive application of locally available building materials. Please note that not every wall thickness can be realised with standard formwork panels. It can even be used in areas with poor load-bearing soil. After removal of the moulds, the window frames can be painted and glazed. Water piping can be installed in the wall, and where required, openings in the wall can be made to allow pipes to pass through the wall. Wall structure with roof structure in place. The depth of the edge beam should be at frost free level. I am thinking a person could assemble a jig to drill holes in foam panels and insert short pieces of steel tubing into the holes in the foam. Create an energy-efficient and sustainable building with SmartBlock Insulated Dimensions of layouts must be based on the possibilities of the selected or available mould system. This will be sufficient for almost all layouts under all occurring conditions. The characteristics of the mould and the foam concrete must be taken into consideration. I read in one of your articles when putting up rigid fome to Install two inches of rigid insulation board directly against concrete. (Engineer’s design) Starter bars tie the walls solidly to the foundation. The two things that excites me the most about SCIP as an alternative building method is, 1.) I have spent some time with ferrocement boatbuilding that uses mesh over steel frames to build a strong cement boat hull. Foam concrete is a type of lightweight concrete that is manufactured from cement, sand or fly ash, water, and the foam. Where applicable the use of in-house heating and/or cooling can be reduced thanks to the insulating properties of CLC. After stripping the wall moulds, the roof structure can be placed and fixed to the walls by using the cast-in anchors. In foam concrete, all coarse aggregate (gravel) and part of the sand is replaced by air, resulting is substantial reduction of materials. Local materials  and products are used as much as possible. How to Form Concrete Walls. When window frames are used, counter profiles must be attached to the mould so that the window frame can be placed quickly and accurately. because the roof is one piece there is no way for a shingle to come off during a hurricane and create a weak spot that would cause you to lose your roof. In tropical and sub-tropical regions cross ventilation at ceiling height can be provided with these ventilation blocks. Walls made with ICFs withstand more than 4 hours of continuous fire and remain structurally sound protecting your home and belongings. The use of moulds result in very fast production of huge amounts of products. It is better to have the same layout with a different colour wall finish, than a different layout with the same colour. ROBBMOFFETTPOSSUM LIVING In The 21st Century  This site is a collection of personal pages fo. Full automatic machines for CLC. I have looked into every low cost method I have ever ran across and the SCIP method looks like it would be the best for me. A mold expert told me to put the board on top of the framing, not directly onto the concrete wall so the house can breath. Foam concrete consists of sand, cement, water and foam (air) and is used for all walls. In areas of increased stress additional reinforcement bars will be required, such as around openings in the wall. the walls and roof do not need to be painted simplifying maintenance. of concrete core and 2.125 in. A.2.7 Ceiling 3)The roof Further reduction of material is achieved as the walls are of nominal thickness and do not require plastering on inside and outside. The contractor, however, installed solid Neoprene control joint fillers like those typically used in concrete masonry walls. Electrical installation can also be fixed to the wall surface as cellular concrete is suitable to be nailed and screwed.
