Improving some of the physical properties of building blocks by adding porcelain in different proportions

One innovative method that has been widely used over the past few decades is the production of heat-treated compressed earth bricks, which are low-cost and environmentally friendly. The aim of the current manuscript is to study the geotechnical properties of rammed earth bricks collected from four areas in Diyala Governorate, namely Baqubah, Al-Muradiyah, Khan Bani Saad, and Al-Rashidiyah, after placing the collected samples in special bags afterwards. The locations of each sample were determined using a GPS device. A mixture of soil samples taken from the study area was prepared to form a good soil mixture after grinding it well and sifting it with a sieve (2 mm). Then water was added in gradual proportions and it became a good mixture. It was dried and ground again after adding porcelain in different proportions (0, 5, 10.15%).). The soil mixture was mixed wet and then the samples were compressed under pressure (8 tons). Samples are placed in the oven at a temperature of 900°C for two hours to produce all models. All brick models produced are then dried naturally at room temperature for 28 days to undergo thermal insulation testing.
