Claims

Revised 08/10/2018, Page 1 of 1. Claims: 1. High-temperature resistant lightweight concrete blocks consist of Water : Portland Cement Type 1 : Pumice : Rice Husk Ash : Serpentinite. 2. High-temperature resistant lightweight concrete blocks as per Claims 1, where the ratio of Water : Portland Cement Type 1 : Pumice : Rice Husk Ash : Serpentinite is: - Water 87.5 - 100 kg/m³ - Cement 200 - 250 kg/m³ - Pumice 100 kg/m³ - Rice Husk Ash 25 - 50 kg/m³ - Serpentinite 25 - 50 kg/m³. 3. Manufacturing process of high-temperature resistant lightweight concrete blocks. According to Claim 1, the process involves the following steps: A. Pumice stone is sized to 75-4750 microns (symbol). The pumice is then soaked in water for 6-8 hours, and then dried on a dry cloth for 1 hour. This process yields saturated lightweight aggregate. B. Serpentinite and rice husk ash are ground and sized to 45 micrometers (375 mesh). This process yields the binder. C. Ordinary Portland Cement (Type I), the saturated lightweight aggregate from step A, and the binder from step B are mixed in the specified ratio. Sample bricks are then cast into molds for 24 hours. After 24 hours, they are removed from the molds, wrapped tightly in clear plastic, and stored in a temperature-controlled room (28-30°C, 70-80% relative humidity) for 28 days. The plastic is then removed. This process yields high-temperature resistant lightweight bricks. ---------------------------------------------------------------------------------------------------- ------27/11/2017------(OCR) Page 1 of 1 page Claims 1.

Manufacturing process of high-temperature resistant lightweight concrete blocks. According to Claim 1, the following steps are involved: A. Pumice stone is sized to 75-4750 microns (symbol). The pumice is then soaked in water for 6-8 hours and then surface-dried on a dry cloth for 1 hour. This step yields saturated lightweight aggregate. B. Serpentinite and rice husk ash are crushed and sized to 45 micrometers (375 mesh). This step yields the binder. C. Ordinary Portland Cement (Type I), the saturated lightweight aggregate from step A, and the binder from step B are mixed in the specified ratio. Brick samples are then cast into molds for 24 hours. After 24 hours, they are removed from the molds, wrapped tightly in clear plastic, and stored in a temperature-controlled room at 28-30°C with 70-80% relative humidity for 28 days. The plastic is then removed. At this stage, high-temperature resistant lightweight concrete blocks are obtained. ------------ Page 1 of 1 page. Claims.

1. High-temperature resistant lightweight bricks consist of: water: cement: pumice: rice husk ash: serpentinite.

2. High-temperature resistant lightweight concrete blocks, as per claim 1, where the ratio of water : cement : pumice : rice husk ash : serpentinite is: - Water 87.5 - 100 kg/m³ - Cement 200 - 250 kg/m³ - Pumice 100 kg/m³ - Rice husk ash 25 - 50 kg/m³ - Serpentinite 25 - 50 kg/m³

3. The manufacturing process of high-temperature resistant lightweight concrete blocks, as per claim 1, consists of the following steps: a. Pumice stone is sized to 75-4750 microns (symbol). The pumice stone is then soaked in water for 6-8 hours and then laid on a dry cloth to absorb excess water for 1 hour. This step yields saturated lightweight aggregate. b. Serpentinite and rice husk ash are ground and sized to 45 micrometers (375 mesh). This step yields the binder material. c. Ordinary Portland Cement (Type I), the saturated lightweight aggregate obtained from step a, and the binder obtained from step b, in the specified ratio, are mixed thoroughly. Sample blocks are then cast into molds for 24 hours. After 24 hours, they are removed from the molds and wrapped completely in clear plastic. Store the bricks in a temperature-controlled room at 28-30 degrees Celsius with 70-80% relative humidity for 28 days. Then remove the plastic packaging. At this stage, you will obtain lightweight concrete blocks that can withstand high temperatures.
