To start with, the size of the EPS beads, the amount of water used and the other admixtures used will change the weight, density, and R value of the epscrete. So, you will have to determine what …
Lightweight concrete, also known as EPScrete (expanded polystyrene concrete), is a material widely used in the building of environmentally "green" homes. The substance is often made using small Styro balls as a lightweight aggregate instead of the crushed stone that is used in regular concrete.
Calcium silicate is the main component of Portland cement. So, you are getting more cement to bond with the EPS beads. Concrete Fiber Is for Bonding. Not for Preventing Segregation. Additionally, steel, polypropylene, treated fiberglass, or any approved concrete fiber can be used to bond the EPScrete together.
Cast-in-place concrete typically has an R-value ranging between 0.08 and 0.10 per inch, similar to other types of poured concrete. The specific R-value can vary depending on factors such as the mix design, curing conditions, and aggregate used.
One of the main advantages of tilt-up concrete panels is their low R-value (0.08 per inch). This means that tilt-up concrete panels have very little insulation value, allowing energy to flow roughly 60x faster than insulation. However, this is a major downside as it makes them very susceptible to heat and cold damage. In addition, tilt-up ...

What is R-Value? R-value, commonly used when describing walls, roofs, and similar housing components, measures how well building insulation can prevent the flow of heat into and out of the home. A higher R-value equates to greater insulation performance, and thus higher savings on heating and cooling.
The table below provides a general idea of the R-value for various thicknesses of normal concrete slabs: R-value of 1 inch of concrete: 0.08. R-value of 4 inches of concrete: 0.32. R-value of 6 inches of concrete: 0.48. R-value of 8 inches of concrete: 0.64. R-value of a 12-inch concrete wall: 0.96

XPS, and Polyiso, with an R-value per inch of R-4, R-5, and R-6 respectively. There are numerous types of connection systems to tie the concrete wythes together includ-ing meshes, grids, and pins. Most connec-tors are non-conductive and do not reduce the thermal performance of the insulation. Two types of insulated precast panels: 1.
The R-value of an uninsulated, 8-inch-thick basement wall built using normal-weight concrete is 1.35, based on data from the 1993 American Society of Heating, Refrigeration, and Air-Conditioning Engineers' Handbook. By doubling the thickness of the wall to 16 inches, the R-value only increases by 0.50.
Here are some ideas about using EPScrete vs straw bale and other building methods that I determined from experience and personal research. ... The straw has a high amount of silica just like hemp hurds do. Which will make pozzolan cement just as hemp and lime does. When I investigated doing hempcrete years ago, hemp hurds were …
ICFs provide the shaping, structural form for the concrete and then are left in place to provide remarkable insulation value. Pumice concrete provides an exceptional fit for ICF construction by: 1) Boosting the overall R-value of the wall or deck by adding its 4X R-value advantage over standard concrete to the building envelope.
The higher R-value of ICF provides greater insulation to the building by keeping the controlled temperature for longer periods. This thermal insulation behavior …

The R-value is the insulating capability of a given material. Learn how to measure the R-value of concrete and ways to improve it.
The heavier the EPScrete block mix, the smaller the blocks need to be for hand carrying and placement. Lighter mixes will need more reinforcement. Many people may not have access to superplasticizers, polypropylene fiber, concrete bonding fluids, silica fume or fly ash. All of those can help to make better EPScrete mixes for different …
Precast concrete has low R values which vary based on the concrete's density and other factors. For 144 pounds per cubic feet of concrete, the R value is approximately 0.063 per inch.² As concrete density decreases, the R value increases. Add rigid insulation and you can get an R value of around 5 per inch depending on the type …
