The objective of this research is to find the optimal ratio of glass power (GP) and municipal incinerated bottom ash (MIBA) for producing environmentally friendly interlocking paving blocks. To achieve this, 15 different ratios of mortar samples, sized 5 × 5 × 5 cm, were produced using a 1:3 cement-to-aggregate ratio and a 0.5 water-to-cement ratio. GP was used to substitute cement at 0, 10, and 20% by weight, while MIBA was used to substitute aggregate at 0, 10, 20, 30, and 40% by volume. The samples were divided into two groups and cured with water for 28 and 90 days. Physical testing was performed on the mortar samples after curing. The results show that at 28 days of curing, BA10 and BA20 had compressive strengths of 42.28 and 40.92 MPa respectively, which is higher than the standard for interlocking concrete block (40 MPa) according to TIS 827-2531. At 90 days of curing, GP10BA10, BA10, GP10, GP10BA20, GP20, BA20, and BA30 had compressive strengths of 47.62, 43.63, 43.51, 43.48, 42.73, 42.40, and 40.40 MPa respectively, which also meets the TIS standards.
本研究的目的是找出玻璃粉（GP）与城市焚烧底灰（MIBA）的最佳比例，以生产环保型联锁铺路砖。为此，使用1:3的水泥与骨料比例和0.5的水灰比，制作了尺寸为5×5×5厘米的15种不同比例的砂浆样品。GP以0%、10%和20%的重量替代水泥，而MIBA以0%、10%、20%、30%和40%的体积替代骨料。样品分为两组，用水养护28天和90天。养护后对砂浆样品进行物理测试。结果表明，养护28天时，BA10和BA20的抗压强度分别为42.28MPa和40.92MPa，高于泰国工业标准TIS 827-2531中联锁混凝土砌块的标准（40MPa）。养护90天时，GP10BA10、BA10、GP10、GP10BA20、GP20、BA20和BA30的抗压强度分别为47.62MPa、43.63MPa、43.51MPa、43.48MPa、42.73MPa、42.40MPa和40.40MPa，也符合TIS标准。
