低碳自密實(shí)混凝土基礎(chǔ)與應(yīng)用
本書旨在為研究人員、工程師和學(xué)者提供一份詳盡的指南，以應(yīng)對低碳自密實(shí)混凝土的設(shè)計(jì)和性能研究挑戰(zhàn)。主要內(nèi)容涵蓋了多個(gè)方面，包括自密實(shí)混凝土的基本性質(zhì)、性能研究、原材料特性、設(shè)計(jì)方法、仿真分析和機(jī)器學(xué)習(xí)應(yīng)用。本書深入探討了基于顆粒堆積理論的設(shè)計(jì)原則，介紹了可壓縮堆積模型和修正模型，以及討論了如何優(yōu)化骨料級配以實(shí)現(xiàn)低碳自密實(shí)混凝土的設(shè)計(jì)目標(biāo)。最后，還介紹了最新的機(jī)器學(xué)習(xí)方法，用于低碳自密實(shí)混凝土的建模和性能預(yù)測。本書將提供實(shí)驗(yàn)室測試、仿真分析和實(shí)際應(yīng)用案例，以幫助讀者更好地理解和應(yīng)用這些方法。
