全国化学周10月18日至24日举行 今年主题「建造中的化学」 适逢美国化学会成立150周年
2026年全国化学周（National Chemistry Week）于10月18日至24日举行，由美国化学会（American Chemical Society，ACS）主办，今年主题为「建造中的化学」（Chemistry Under Construction），聚焦化学在建筑材料与日常结构安全中的作用。2026年适逢美国化学会成立150周年，本届化学周的科普刊物《Celebrating Chemistry》封面以钢、砖、木三种材料搭建「150」纪念造型，呈现不同材料的化学性质与用途。
美国化学会介绍，混凝土、钢材、玻璃与沥青等建材的强度、安全与耐久程度，都取决于其化学组成：水泥中的硅酸钙赋予混凝土强度，钢材中碳与合金元素的比例影响其性能，材料成分的细微变化即可改变强度、凝结时间与抗风化能力。该会指出，混凝土是地球上消耗量第二大的物质，仅次于水。
全国化学周是美国化学会发起的公众科普宣传活动，旨在向公众推广化学在日常生活中的价值，由全美各地分会与化学爱好者统筹组织活动。据该会数据，其地方分会参与率超过89%，《Celebrating Chemistry》发行量超过17.5万份，活动触达超过3,500万人次。本届化学周期间，该会将于10月21日晚举行线上主题活动「Program-in-a-Box」，与各地观众共同探讨建造材料背后的化学。
National Chemistry Week Runs Oct. 18-24 With Theme 'Chemistry Under Construction' as ACS Marks 150 Years
National Chemistry Week 2026 runs October 18-24, organized by the American Chemical Society (ACS) under the theme "Chemistry Under Construction," highlighting chemistry's role in the strength, safety and durability of everyday structures. The 2026 observance coincides with the 150th anniversary of the ACS, and the cover of this year's Celebrating Chemistry magazine builds a "150" statue from steel, brick and wood to show the chemical properties of each material.
According to the ACS, the performance of construction materials such as concrete, steel, glass and asphalt depends on their chemical composition: calcium silicates in cement give concrete its strength, while carbon and alloying elements shape the performance of steel, and small changes in composition can alter strength, curing time and resistance to weathering. The society notes that concrete is the second most consumed substance on Earth after water.
National Chemistry Week is a public awareness campaign run by the ACS to promote the value of chemistry in everyday life, with events coordinated by local sections and chemistry enthusiasts nationwide. The ACS says more than 89% of its local sections participate, Celebrating Chemistry reaches over 175,000 issues, and the campaign's reach exceeds 35 million. During the week, the society will host its "Program-in-a-Box" online event on the evening of October 21 to explore the chemistry behind construction materials.
